37.1 | Replaced boot | LUDWIG::STANDING | | Thu Aug 29 1996 10:02 | 7 |
| WSTK.1 Replaced the bellows boot over the unload station dump
valve. After assembling the valve with no leaks, the valve did not
cycle back up to fill the tub. Located TR2,3 and relay cr17 inside
the fluids cabinet, under the top lip. Found that TR2 was not
opening due to the time delay resistor not making good contact
inside the spade terminals. Crimped spade connector and connection
was reestablished. Dump valve then started working normally.

37.2 | gGIGLIST | LUDWIG::WESTPHAL | | Fri Aug 30 1996 21:13 | 22 |
|
CMP.C1 - Engineering made a list they want completed by this coming Tuesday.
1. Load alignments
2. Unload alignments.
3. Chillers filled
4. Check if platens come up to temperature
5. Repair the final wetting ring
6. Do the sweep alignments for both tables
7. Arm alignments
Topped off the chillers but never checked if the platens temperatures.
Tried to transfer wafers but the tool would not even try to pick a
new wafer. Found that the center bolt for the load cup was so tight
that it was binding and not making its sensors. Tried to again "load
a new wafer" But crashed wafers. The jam sensor is obviously not
working. The wafers were not sensing properly in the load cassette.
Adjusted the optical sensors. Final got the a wafer to load but the
arm kept erroring for an arm Lifting error. Adjusted the air flow to
the arm up/down cylinder and rebalanced the arm. Transferred wafers
from load to unload with several different problems and errors.
Tool presently sets powered off.

CMP.C1's Hit List Update
------------------------
1. Load alignments
ok 2. Unload alignments.
ok 3. Chillers filled
ok 4. Check if platens come up to temperature
needs to be checked 5. Repair the final wetting ring
6. Arm alignments
CMP.C1 - The final platen was not heating. The chiller had a low glycol level
and the indicator lamp was burned out. The bulb was replaced and the
chiller topped off. Platen heated with out a problem. The upgraded
shuttle jam sensor was installed but there was not enough time to
properly adjust it. The water track to cassette alignment was also
completed. Tool sets still needing the load handler and arm
alignments. Mike Standing and Myself will be in on Tuesday to do
them. Tool power and DI is off.
|
37.4 | Shuttle Jam not working | STRATA::STANDING | | Tue Sep 03 1996 20:37 | 4 |
| CMP.C1-7 Troubleshooted the new shuttle jam sensor installation.
Found that U4 and the relay KIL were working, but seemed to be sticking
for some unknow reason...Checked stock for new ones had none. Called
WESTECH tech support got none. Will try again in the morning.
|
37.5 | WSTK START-UP WORK CONTINUED. | STRATA::WESTPHAL | | Wed Sep 04 1996 21:05 | 9 |
| CMP.C1 - Continued with the install of the shuttle jam sensor. Suspect that
we are missing part of the new shuttle kit. This is being checked on
and the parts will be ordered as needed. Most of the handling
alignments have been completed but a few adjustments are still
necessary. Losing wafers on the primary pad. Carrier film was gouge.
The carrier was rebuilt and reinstalled and with some changes to the
recipe this problem has been corrected. The primary heat exchanger
was leaking. Did not have time to address this issue.
|
37.6 | WSTK START-UP WORK CONTINUED. | LUDWIG::WESTPHAL | | Thu Sep 05 1996 21:16 | 4 |
| CMP.C1 - Continued to prepare the WSTK for process engineering. The Alignments
were completed. Tool sets needing the down force calibration and some
minor handling problems worked out. The rest of the install kit for
the shuttle jam sensor has been requested from Westech.
|
37.7 | START-UP | STRATA::WESTPHAL | | Fri Sep 06 1996 20:44 | 3 |
| CMP.C1 - Continued with the start up. Shuttle jam sensor is now
operating properly (Thanks to Mike Standing). Alignments and
calibrations are complete.
|
37.8 | Ready to run process | LUDWIG::STANDING | | Sat Sep 07 1996 18:24 | 8 |
| CMP.C1-7 Continued with the startup. Finished the shuttle jam
install. Adjusted load elevator home switch, shuttle hard stop, wafer
prespray to 1 sec. Adjusted the unload track water exit and bowl
water. Adjusted the wafer in track sensor gain. Ran 75 wafers with
out any errors before finishing. Tool has been wiped down and is ready
to run process. NOTE! Do not power down tool! The motor for the
primary heat exchanger will not restart! A new motor should be rushed
in, A.S.A.P.

37.10 | PROJECTS | STRATA::WESTPHAL | | Fri Sep 13 1996 19:52 | 5 |
| CMP.C1 - Continued with the project list. Connected the a piece of hose to the
return for the day tank to avoid splashing. Repaired the polish tub
rinse ring. Installed a new 30" vacuum/pressure 30 psi gauge to the
carrier. shut the DI of to the tool due to the fact the line will be
purged.
|
37.11 | projects. | LUDWIG::WESTPHAL | | Wed Sep 18 1996 20:19 | 6 |
| CMP.C1 - The second polish conditioner was slopping around. The bolts
were bottoming out. Cut the bolts and reinstalled with no further
problems. Installed a clip to hold the final rinse ring flat against
the table top. Moved the slurry drum and pump into the room but did
not hook it up.
|
37.12 | Day tank / Carrier wetting. | STRATA::WESTPHAL | | Thu Sep 19 1996 20:53 | 3 |
| CMP.C1 - Poly welded a small piece that secures the slurry return to
the day tank. Also having some problems getting the carrier wetting to
work while the tool is idle. No conclusion was reached.
|
37.13 | Final table condition arm sweep hooked up | SUBPAC::LANDRY | | Mon Sep 23 1996 18:28 | 10 |
| Today.....
The condition arm for the final table was setup to utilize the
sweep motor. The motor power was re-connected and the "set-screw"
mechanical stop was removed from the motor housing. Also, the small
diamond disk was re-installed to allow proper sweep movement. Upon
checkout, the conditioner would bounce occassionlly. The air input
was reduce to <10 psi to eliminate the problem. All's working fine.

37.14 | SHAFT HEIGHT ADJUSTED | STRATA::WESTPHAL | | Sat Sep 28 1996 22:11 | 7 |
|
CMP.C1 - Adjusted the shaft height as requested by engineering. The shaft
height was .740. The new pad height is .022. The shaft height is now
.772 (actual .775). A new button was installed. The tool presently
sets all put back together, out of wet idle because that was how it
was found.

37.15 | VACUUM PROBLEMS | SUBPAC::BJUBINVILLE | CMP-6 Equipment Engineering | Tue Oct 15 1996 23:25 | 12 |
|
WESTECH - DROPPING WAFERS OFF THE CARRIER
FOUND WE WERE GETTING ONLY .375 IN OF MERCURY VACUUM TO THE CARRIER.
FOUND NO CLOGS OR VACUUM LEAKS. CHECKED WATER PRESSURE TO THE
TO THE SYSTEM AND NOTICED WE WERE DROPPING 5PSI IN THE FILTER.
REPLACED THE CLOGGED FILTER AND THE VACUUM WENT UP TO .540 IN OF
MERCURY. MANUALLY CYCLED WAFERS THROUGH WITH NO VACUUM ERRORS.
WE WERE NOT ABLE TO AUTOMATICALLY LOAD A WAFER UNTO THE CHUCK.
COULD FIND NO OBVIOUS PROBLEMS. THINK IT MIGHT BE OE ON OUR PART.
SHERMAN WANG WILL NEED TO CHECK OUT SYSTEM COMPLETELY FOR PROPER
OPERATION TOMORROW.

WESTECH - WAFER LIFT KEEPS ON JAMMING
REMOVED THE WAFER LIFT, DISASSEMBLED AND CLEANED WITH ISO AND DI
WATER. INSTALLED THE WAFER LIFT AND CYCLED ABOUT 4 WAFERS THROUGH
WITH OUT PROBLEMS. IT WAS STARTING ON THE 5TH WAFER AND THE
SYSTEM ALARMED FOR WAFER NOT ON CARRIER. NOTICED THE LIFTER WAS
NOT STAYING UP ALL THE WAY. TOOK THE CUP OFF AND RAN THE LIFTER
UP AND DOWN AND SAW THE THE LIFTER WAS NOT HOLDING PRESSURE IN

--------------------------------------------------------------------------------
System was down because the wafers would not load, meaning they would
not transfer from the load cassette to the lift cup. Found spindle
controller breakers tripped. Reset them, system runs fine.
Item of note, the tool box combo has been changed due to "pilferage."
See me for the new combination.

TRIED TO CLEAR ALARM WITH THE PINS EXPOSED. THE ALARM WOULD STILL
NOT CLEAR. REMOVE THE FRONT PANEL TO EXPOSE THE WIRING AND
FIND WHICH WIRES WERE GIVING US THE FAULT. FOUND THE TWO WIRES
THAT WERE GIVING US THE CONTINUOUS FAULT AND REMOVE. THE SYSTEM
WILL RUN FINE WITHOUT THE LOAD CELL CONNECTED FOR NOW. TIM IS
IN CONTACT WITH WESTECH TO RUSH A LOAD CELL IN. THE SYSTEM IS
AT A WARNING UNTIL THEN.

-< Lifter sensor problem >-
--------------------------------------------------------------------------------
Wstk.1 The wafer sensor that is mounted in the lifter does not
operate. This sensor is a fiber optic type and thus the reciever
portiion has a break in the fiber optic part of the sensor. We were
unable to splice the fiber optic together therfore odering a new assembly.
Senor due in tomorrow. I will leave the parts there if someone can come
up with a splice kit.
This was not the original problem. The system went down because the
carrier did not sense a wafer when it tried to pick it off the lifter.
We adj the lifter speed to see if this would fix the problem but was
unable to test due to the sensor problem.

-< Platens off >-
--------------------------------------------------------------------------------
Wstk.1- Is up, when production came in this morning they found the
system down. The platens were off and slurry was all over them.
The CB for the platen drives had to be reset. This condition is
usually caused by the system being EMO'd then powered up too soon.
You know this has happened by going to the 24 volt panel and not seeing
relays 4a and 4b lite behind the CPU card cage.

--------------------------------------------------------------------------------
WSTK.1 - Down for wafer transfer problems.
The wafers were hanging up in the exit water track. Removed the
exit jets and cleaned the track. We put some shims between the
bottom of the track and the jets. The heavy white boats are also
giving us problems. The heavy boats are to muck for the exit
indexer to hold. The wafers tilt forward and slide out of the
boat. This causes the wafers to hang up on the bottom of the
exit track. JMZ/MS

-< testing di flush solenoid >-
--------------------------------------------------------------------------------
Wstk.1 - Has low etch rate, Sherman suspected the primary flush
solenoid was leaking by diluting the slurry. We found this not to be
the case, disconnected the flush solenoid electrically (DI rail#2
wire# 152). and there was not di flush which meant the solenoid was
closing. Tim is presently testing the slurry.

-< more on low e.r. problem >-
--------------------------------------------------------------------------------
Wstk.1 - Etch rate is still very low. We checked the down force press
and it needed a minor adj. The slurry was tested and it
appears watered down. Presently we are having incoming slurry
from bulk fill tested. The slurry we already had tested came
right from the dispense nozzle on the platen. We also looked
into seeing if the DI water was contaminating the slurry.
Checked where any DI valves come in contact with slurry. There
is one DI line by the tank and it was shut off with no signs of
water seeping by. The valve used for purging out the slurry lines
were disconnected at the output side of solenoid and there was no
DI slipping by there either. The line tying into the new system
is shut off and also appears empty of any liquid.

-< low removal >-
--------------------------------------------------------------------------------
WSTK.1 - down for low polish rate.
Called the lab and found the slurry PH at 9.1 This is a low reading
Dumped the slurry out of the PH tank and refilled with new slurry.
Ran a polish rate test and the removal was around 600. Switched
to pump two and ran the same test and the removal rate was around
900. Saw the hole in the dispense tube for pump one was
partially clogged. Cleaned out the tube and ran another polish
rate test. The rate was still around 600 with pump one. Changed
the pad and ran another removal rate test. It was still low. The
pad conditioner appears to be OK. Suggest a slurry sample be
taken from: Pump 1, pump 2, and the PH tank itself. JMZ/Ceasar

--------------------------------------------------------------------------------
Wstk.1 - Was down for uniformity, the polish rate was low in the
middle. We checked the arm sweep and it was off .008". Adjusted
set screws on top bearing for this issue. Next we did carrier sweep
/runout and it was out by .005". Also noted was the carrier height
adj shaft was off and the whole arm was not parallel to the platen
so instead of just adj the gearbox shims we adj the turnbuckle on the
lower elbow link. This brought in the carrier sweep/runout right to
0. A thing to remember is the arm parallel to the platen should be
checked before any sweep leveling is adj.

-< clean station not draining >-
--------------------------------------------------------------------------------
Wstk.1 Clean station not draining fast enough. Put work order in that
we wanted to modify plumbing under clean station so it drained faster
and more completely (Water is draining from cleanstation but some of
the water is being trapped in the plumbing below. Showed Bill Kurz from
facilities what is happening. He had his folks do a quick fix only to
speed the time in which takes to drain the tank. The tygon part of the
drain that was just hanging there is gone. So now it is a straight
shot from the bottom of the clean station to the pvc plumbing. The
clean station now drains faster but this is a simple temporary fix.
The pernament fix is going to take a lot work and designing. The
biggest problems are we have drains going up hill and to small of
piping thus impeding the flow. Next week we will sit down and draw
up a plan that will work.

Good morning,
WSTK.1 --� The transport arm jammed
into the input cassette while trying to go to "shuttle
to elevator position". While the shuttle was pulling a
wafer out of the cassette it pulled the next wafer
out of the cassette enough so that the through beam sensor
did not see it. Then the transport jammed on the next
wafer. This happened a second time while I was watching it
cycle.
I adjusted the shuttle stop
and limit switch on the load cassette side so that the
shuttle is centered under the wafer. I then cycled 50
wafers and it tested good. The system is UP in RTC.
No other equipment issues...
Mark was out.

-< Low center PR/old pad >-
--------------------------------------------------------------------------------
WSTK.1 - Down for low center polish rate. The primary pad was near 3
weeks old, it was replaced. The carrier was replaced with a new 6u convex
curvature carrier. The center PR is now fast, the system was put down
for high uniformity again. This was incorrect, we actually desire a fast
center rate due to the incoming oxide film layer which is center thick.
The conditioner plate was adjusted to control rate drop off from 1st to
last wafer.
Note: When the pad life is near it's end, the center of the wafer is the
first place where the polish rate will drop due to clogged pours. Also,
a new pad must be broken in before running a lot.

down play when in the down position. The cam follower was mounted too
close to the carrier arm post, adjusted same. Also adjusted lock over
arm and calibrated down force.
The following alignments/adjustment were made:
Pre Post
Level +/-.350 +/-.003
Sweep +/-.015 +/-.004
Run out +/-.016 +/-.003
Next:
System errored for arm not down, the arm down switch was adjusted.
Uniformity was checked, it came in at 15%. The carrier was changed
and the uniformity came in at 17%. The carrier curvature will be
changed to decrease the center polish rate.

slurry. Slurry tank was empty so I filled the tank. Slurry
still would not flow. Noticed final flowed rinse water
when rinse flow was on for the primary. Flowed slurry on

--------------------------------------------------------------------------------
Good morning,
WSTK.1 --� I worked with Bob Francis on a
problem with carrier vacuum. The carrier arm would pick
the wafer up, sense vacuum then loose vacuum. We replaced
the carrier assembly and this fixed the problem. During
troubleshooting, a wafer broke on the final pad. We also
noticed that the system was making noises when the carrier
was on the final platen. There are 4 new final pads that
we got out of the stockroom in the westech room.
Misc --� I placed a call to 4141 because
there is water leaking into APL through the hepa filters,
and near the light fixtures.
Facilities removed the water from
above the filters and wiped down the walls. There is still
some residual water in the hepa filters, but they should
dry out.
No other equipment issues.

WSTK.1 - Down for primary condition arm jumping up and down.
Found the Primary condition arm jumping up and down during the
condition cycle. Noticed the motor stopping and the arm lifting
up. If we held the limit switch, it would work correctly.
Adjusted the limit switch and was able to manually run the pad
conditioner. But the conditioner was not working automatically
when cycling wafers. Swapped sol 29 with 40 (primary with final)
Cycled wafers through without further problems. note** We need
to replace the sol for the final conditioner.

on the Guide Rods for the Shuttle. The Slurry made it difficult for
the shuttle to travel smoothly to the lift and it was slamming into
the sensor, which moved it. I cleaned the Guide Rods and adjusted the

REVIEW OF THE HIGH PARTICLE PROBLEM. 6/29/93
The system was put down on Sunday start up 6/27 with particle counts
of 3000. On the previous Friday 6/25, the new style end effector was
installed and a monthly pm performed. To go back to square one, the
new end effector was removed, both pads changed load and unload are
cleaned and slurry tank was washed out. Particles came in at 178. We
were looking to achieve <100, this is what was achieved ion the past.
EXCEPT these low readings were on product wafers and read on the 7000.
The monitor wafers are not polished as long and are read on the 6200.
We will continue to monitor monitor particle levels with the upper
control limit set to 500.

Wstk.1-Down for wafer vacuum not being sensed on the carrier.
Production and process engineering have seen the problem many
times today. At first they thought it was the wafers because it
seemed to happened on just WJ wafers. Then we saw it happen once
and what we noticed was the wafer was not sitting in the pocket
of the carrier. Therefore we have been looking at the loading
of the wafer especially coming into the lift. Have been running
many wafer tranfers with no problems seen.

WSTK.1 - down- for Carrier vacuum not achieved.
Changed the carrier and cycled two boats of wafers through without
further problems. On the third boat of wafers we left the system
and came back to a wafer smash on the primary pad. Did not see
why the wafer broke, but there was a wafer in the carrier when we
arrived. The only explanation was there was two wafers stuck
together in the load cassette and the tool loaded both of them
as one. We cleaned up the mess and replaced the carrier and the
primary pad. A vacuum/pressure gauge has been installed on the
tool and a boat of wafers were cycled without problems. Turned
system over to mfg for full mqc's

WSTK.1- Down for carrier vacuum not achieved
Found the wafer was being placed on the carrier to one side and out
of the pocket. Adjusted the lift over and still had the same
intermittent problem. After several test and alignment tests, It was
concluded the alignment was good and the problem was happening
during the lift to carrier. Turned up the N2 to the system and was
able to increase the secondary reg to 80 lbs. It was originally
sitting on 70 lbs. We also turned down the load spray from 1 sec to
1/2 sec. With those two changes, were were able to cycle 3 boats
of wafers through without further problems. The system was turned
over to MFG and a removal rate was done. The removal rate is still
low at 800. Mfg decided to run with it and ran both lots without
any problems.

-< Wafer loading problem >-
--------------------------------------------------------------------------------
WSTK.1 - Passdown stated that wafer lift needed replacement without
any explanation or reason. Checked wafer lift out and only
fault noted was the lift to load vibrated when it retracted.
The lift to load assembly was replaced and the new part had
the same symptoms. The pneumatic switch (SOL9) has a pre-
sicion flow valve (PRV17) on its input. PRV17 was adjusted
and the lift operated smoothly. Tried running wafers and
the carrier did not pick the wafer from the load station.
Noticed the load station move down slightly when the arm
came down to load. Again adjusted PRV17 and the system ran
without error.
The system pressure was adjusted from 70 to 80 psi
last thursday. The PRV17 adjustment is sensitive so this
might have thrown it off.
The primary and final pads were replaced.

samples were taken. The tank in the chase was low at 10% solids. The
tank out back was mixed and than sampled, it read 12%. The chase tank
was drained and refilled, polish rates came in spec at 1060a/m on
7/2/93. Again on Thursday 7/8/93 low polish rates were experienced,
@900a/m. Samples taken again showed the chase tank was at 11.5%. Again
the tank was dumped an refilled. Polish rates came in at 1200a/m. This
problem will be eliminated by modifying the bulk system to constant

Cup flush to each other. I also had another Carrier rebuilt, then
installed it. A full cassette of wafers was run with no problems.

NO VACUUM AT LOAD CUP....
NO WAFERS could be picked at the load cup, system did not reach vacuum.
The arm stabilizer DO was on but the stabilizer air cylinder was not
acuated. This was letting the arm go limp in the upward direction,
causing the wafer to not sit firmly in the pocket of the carrier.
The needle valve for the stabilizer cyclinder was adjusted. Next the
system had high particles @1700. The wafer was hitting on the two of
the cup's depressor pins. Both shuttle stops were adjusted; the shuttle
at cassette and the shuttle at load cup. The wafer now drops into the
center of the load cup. Both pads were replaced, they became dry. The
next particle check was in, near the UCL.

The access code is 456. The MFG access code is 222.
For high particle:- Clean the entire tool thoroughly with DI, especially
the load area (all parts). Remove all slurry build up.
- Dump the clean station and refill (DI/DO page 3)
- Dump the exit tank several times.
- Replace both pads (with zero bubbles), rinse both pads
with DI water. Have MFG Run 10 or so oxide monitors wafers
with the "Warmup" recipe.
- Recheck particles.
Low Polish rate: - Replace the Primary pad and conditioner
- Drain the Slurry tank and refill.
- Recheck the rate.
- If bad: verify platen speed and carrier speed.
check down force.
Handler problems: - Check error page for what type of failure.
- check to see that the carrier is sitting in the load
cup properly.
- Check vacuum gauge, should read ~20"
- If low check vacuum line for leaks and check Soft water
filter on the chase wall. If this is clogged there
will not be enough water flow to create a good venturie
vacuum.
- If there is good vacuum and the wafer is not staying
in the pocket, have MFG replace the carrier.
Uniformity high (greater than +15% or less than -5%)
- How old is the carrier?.....have MFG try new carrier.
- Replace primary pad.
- Check again.
- Check alignments (Trained personnel only)

The vacuum for the wafer Carrier came on before the arm moved all
the way over to the Primary platen edge after being polished on
every wafer. Adjusted the flow valves for the arm up/down motion
since the arm was moving up slow. This helped out a lot. The Arm
balance, the water track, and the load cassette present switch
were adjusted also. Cycled several wafers through with no more

2nd) Adjust Arm Level. 3rd) Adjusted Platen Sweep over both Platens.
4th) Performed Carrier Runout. 5th) Adjusted Down Force. We had some
difficulty performing the Carrier Runout, because the 90 Degree Box
does not sit perfectly in the Arm. So we leveled the Arm .007 inch lower in
the front than in the back. This allowed for the Carrier Sweep be
+or- .003 inch, which got it in spec and did not affect the Platen
Sweep.

--------------------------------------------------------------------------------
WSTK.1 - Down for loss of wafer backside control and shuttle control
When the backside pressure was enabled in the recipe, the system would
do a cpu dump. The system would come up to a DOS prompt. We tried to
run the system with the backside disabled, but we encountered a
shuttle jam. Was not able to clear the shuttle jam on the screen.
Disconnected the load cell leads to the amp board and was still unable
to reset the shuttle. Jumpered the output wires from the amplifier
board, and was able to toggle the shuttle. The screen would toggle
but the shuttle would not move. Disconnected the air lines to the
shuttle from under the load station and toggled the screen. No air
was flowing. We then disconnected the air lines at the solenoid and
there was air. The air was lost between the solenoid and the piston.
Found a separate set of solenoids that were controlled by the shuttle
force load cell PCB. The PCB need the reset signal to open the set
of solenoids before the shuttle piston. Went to the D.O and found the
signal was getting passed. The wire was later found to be a control
line for the new backside pressure mod. Disconnected the wrong wire
and found the correct wire for the shuttle reset signal stuck inside
the wiring harness. Connected the correct wire up but we still could
not reset the shuttle jam. The shuttle jam pcb must be blown from
running the backside signal to it. Had to jumper the entire board
out in order to move the shuttle back and forth. The tool will not
run wafers correctly do to backside signals passing thorough the
Shuttle reset D.O. The software must of been changed by the reps to
do this. Westech has been notified and will be in tomorrow.

The arm was stuck in the down position and was not going back up

on the table. After that we found the arm hitting the new edge
rinse ring and not continuing to the edge for the wafer lift. The
new rinse ring has a smaller opening for the carrier than the old
one. Look for scribes near the dispense arm in order to line rinse
ring up properly. We later had problems with the wafer sticking
in the water track. Adjusted the bowl jet, exit jet and the wafer
eject. Cycled numerous wafers through without further problems.

-< Backside air upgrade >-
--------------------------------------------------------------------------------
The reps came in today to install an upgrade to the backside air
modification. The location of the backside air AO was changed from
DT 2815 board to the analog rail zero position 10. The EPROMs were
also changed to allow communication to the AO position. PREV1
(Backside air) was calibrated. The .5 micron filter for the backside
air needs to be changed but we have no such filter in the stockroom.
The rep said he would send one to HLO. Due to the amount of time the
system was powered off, the pads dried out and need to be changed.
The system should be ran until the system has been fully tested and
no problems remain.

-< WSTK.1 - Wrong Eproms. >-
--------------------------------------------------------------------------------
WSTK.1 - Ran some wafers after the install and ran into a problem. The
conditioner would not activate. It worked fine in manual. The problem
is that the Rep was given the wrong Eproms. The Eproms are the same as
the ones in WSTK.2 which is a different software setup. The Rep put the
originals back in. Ran the conditioner and then some wafers through
with no problems. The alarm DT2815 failure on the Alarm page can be
ignored. The Rep said the correct Eproms may or may not arrive tomor-
row. He said he'll give John Maze a call and let him know. Changed
both pads and gave the system back to MFG.

Noticed that there was a washer missing on one of the bolts holding
the water track in place, and one of the springs at the other end
was missing. Replaced both and readjusted the PSC1 sensor for the

WSTK.1 - The Unload station sensor needed to be adjusted. Some of the
wafers were not being sensed. Turned down the exit bowl jet also.
Another problem was that the Conditioner arm wasn't going to its home
position right away. The arm would raise up stay there for about 4
seconds and then go back down on the pad and go across. It would then
repeat the same thing again before going home. Adjusted FV38 to slow
down the Condition arm which was going up a bit hard and fast. Ran the
Conditioner several times without any problems. WUP.

finished. It was also bouncing on the Platen during the Conditioning Cycle.
I adjusted FV38 for the problem of the Conditioner not staying at Home at the

-< Wafers not being seen in unload station >-
--------------------------------------------------------------------------------
WSTK.1 - Down for not seeing Wafers in Unload Station. I noticed something
very interesting when Wafers were being unloaded. I was watching the
Input/Output Panel on the CRT and the "UNLD WAFER SENSE" was being highlighted
when a Wafer passed through the Light Sensor, but the Polish Arm behaved as if
the Sensor never saw the Wafer. When I moved the Wafer back over the Light
Sensor the Polish Arm would then recognize the Wafer being seen in the Unload
Station. I felt this may be a problem with the 5 V Supply. I monitored the
5 V input to one of the Analog I/O Boards and when the tool was at rest the
input 5 V's was = 5.01v ; when the tool was running it was fluctuating
between 5.01v & 4.98. This is within the Spec., but I adjusted the input 5v
to the Analog I/O Board to 5.1V (the upper limit to the spec.), to be on the
safe side. I also adjusted the Sensor's Gain and the Exit Jet FV 10. I then
ran 75 Wafers over the tool with no problems. The tool is up.

The tool was trying to polish a wafer on the final pad, but the
arm was up in the air and not on the pad. The carrier was spinning
and the timer was counting down. Aborted the step and unloaded
the wafer. Started the process over again and this time the tool
stopped while on the primary pad. The carrier was stopped, the
platen was stopped, and the arm remained down. The tool had an
alarm for arm position unknown. Aborted the process and powered
down the tool. After a few minutes the tool was powered back up and
numerous wafers were cycled through without further problems.

Passdown from 12/22/93....High uniformity center fast 30%
typical readings = center at 1600a/m edge at 1100a/m
Check complete alignment, carrier run out was out by .019" carrier
sweep waws out by .009".Both of these were alligned to within .002"
Uniformity was still high at ~25%. Because the rate is so fast in the
center we suspected that the carrier curviture was to great. We
suspected the carrier film or curvature as the problem. The carrier
press platen temp was droped by 10 degrees, from 275 to 265. This
produced a 2.5u curve instead of a 4.5u curve. The polish uniformity
came in at 11%.
*NOTE- Normaly when the alignment is out, the edge rate speeds up..FYI
That is why we looked towards the carrier or carrier film.

-< WSTK.1 Pad temp too high. >-
--------------------------------------------------------------------------------
WSTK.1 - Down for a high pad temperature. Had to calibrate the Pad
temperature sensor. At ~100 degrees F, it was reading ~134.
Also adjusted the Carrier vacuum switch sensitivity down a
little. Ran about 10 wafers with the DecCmos5 recipe. The
setpoint for the Primary pad temp was 85 degrees, but the
the temp would start at ~68 at the beginning of the polish
cycle and then migrate up to 75 by the end of the cycle. Prior
to running the wafers, we heated up the Primary platen to
100 degrees and then checked the surface with temp meter to
check the difference between the actual platen temp and what
showed on the screen for the pad temp. There was about a 15 to
20 degree difference. To get the desired 85 degrees for the
pad temp on the Primary, maybe the Primary heater will have to
be programmed to go up to a much higher temp instead of the 70
degrees that it usually is set to. Something that needs to be
taken into account is that the platens take a long time to get
up to temp. We didn't time how long, but when we changed the
platen temp to go up 40 more degrees, it took maybe 15 minutes
to get there. Even if the platen works together with the pad
temp sensor, by time the polish cycle finishes, the platen temp
would only heat up a few degrees which would still be lower than
the 85 degrees. The system had a water track error at about 12:30
AM and was fixed. The system is back to MFG.

WSTK.1 -DOWN- While performing Monthly PM two problems occurred. The first was
the Carrier was accidentally dropped and damaged during removal for PM. The
second was discovered when performing Temperature Calibration Checks. We found
The Primary Heat Exchanger was not Turning on when the System sent a DI output
to it. The DI output was making it into the Heat Exchanger, but the heater was
not turning on. The Tank was topped off and the Float Switch was working
correctly. We found the SSR's 3 & 4 were not turning on and allowing the 208V
AC to go to the Heater Core. While trouble shooting we noted the Final Heat
Exchanger in the OFF Mode had 0 V at TB23-7 & TB23-8 to Ground, but when the
Primary was in the OFF Mode we found 24V at TB22-8 (to ground) and 0V at
TB22-7 (to ground). In the CRTL Mode the Final Heat Exchanger had 24 V at
TB23-7 & TB23-8, while the Primary had 24.5V at TB22-7 & 22.7V at TB22-8. This
voltage drop was across CR25. The Voltage reading at TB22-8 goes through CR14
and then makes it to the SSR's. We swapped the Mechanical Relays, but it did
not help us find the problem. We noticed both Heat Exchangers have the same
Functionality , but are wired differently from each other and do not necessarily
correspond with the Prints made available to us.
Please note we used the Engineering Drawing # 372-36267; Heat Exchangers Power

It was suspected that some slurry may have gotten into them and
caused them to stick. Adjusted PSW2 from about 5 volts to 5.3 volts.
There was also a problem with the Carrier wafer vacuum. All of these
problems stopped after the voltage adjustment. The bulk system is now
working. Ran some wafers through and then gave the system back to MFG.

vacuum would go off according to the vacuum gauge, but the screen
showed a vacuum. Made some adjustments to the pressure switch for the
vacuum. The vacuum went off ok after the adjustments, but the vacuum
dropped off during the clean head part of the cycle which caused a
missing wafer error. Another pressure switch has been ordered from the
Stockroom. Will be replaced on third shift.

about the problem and he told me two things: 1) There has been a Hot Line call
made to Facilities to install a drain on the Exhuast Line, which will cure the
problem alltogether. 2) To turn off the DI Water to the Rinse Ring in the

arm up/down air cylinder and toggled the arm up and down to test Sol 1
which supplies the air. The air came on instantaneously with each try.
Tried different pressure settings with PRV5 and adjusted flow valve
(FV1) with no real significant changes in the up motion of the Polish
arm. Pushed against the arm which is attached to the air cylinder and
then commanded the arm to come up. The air cylinder didn't actuate for
about 6 seconds and then the pressure built up. Tried the same thing on

be the air cylinder itself. Found the Vendor # and gave to TDYER since

50 Wafers using the Patrical Recipe without any problems with the Arm slaming as
it lifted off the Primary Platen. The Partical Recipe was the one which was
giving us the most problems before. The system needs to have the Pads I put on
replaced and Full MQC's need to be done. I cleaned the system when I was

cassette, the wafer sensor on the water track picked up on the wafer.
There is no real need to adjust the sensor amp since the amp is very
sensitive to adjustments and no problems will occur from the situation.

-< PCW Water Leak >-
--------------------------------------------------------------------------------
WSTK.1 & WSTK.2 - The PCW Solenoid Valves in the Heat Exchangers were
vibrating so strongly when activated, a 2 Inch PCW Water Line had been damaged.
Site Services contacted us early in the morning and infomred us of the
situation. They also infomred us the fix is temporary, so any further strong
vibrations in the PCW Line may result in the PCW Tank being emptied into the
Westech Room. A different Solenoid Valve was tried in the Primary Heat
Exchanger in WSTK.1 and it worked ten times smoother than the existing style.
The only problem is there was only one of these 24 VDC Valves which could be
used in the Stock Room. A new Solenoid Valve of the existing style was put
into the Final Heat Exchanger of WSTK.1, but it worked just as poorly as the
one it replaced. The system has the Final Heat Exchanger turned off as well as
the Solenoid itself is disconnected. Tim Dyer was contacted at home and he
will be addressing the issue on Monday morning. WSTK.1 can be run as is, and
this information was relayed to production.

A wafer was run, and the problem was still there. The vacuum
was climbing up to about 18 inches of water before lifting up,
and the Polish arm was also going very close to the edge before
lifting. The carrier was taken off and measured. It had almost
no curve on it. Once another carrier was built and put on, 20
wafers were run without any of them dropping off. Gave the system

Platen run out and sweep were good at .001 and .002. checked the
carrier runout and could not read the indicator due to the
misalignment. Found the arm was at a 1/2 in tilt towards the
carrier. Roughly straightened the arm with the load cell so it
was parallel to the platen. Was able to keep the indicator within
.010. Adjusted the arm some more and was able get a steady .004
deflection. Checked the down force followed by the arm balance.

-< water leak and bad vacuum switch >-
--------------------------------------------------------------------------------
WSTK.1 - Down for rusty solution on top of the carrier
Found the water seal between the union and the carrier shaft leaking
water. Did not have another seal in stock so i took a sand stone and
removed the gouges and indentations. Assembled the union back to
the carrier shaft and was able to draw 25 inches of vacuum with wafer
and wafer eject did not leak into the arm. Started to run a wafer
through the system and got an alarm for no vacuum on the carrier.
The gauge was showing 25 inches but the display was at zero. Tried
to adjust the gauge for proper indication,, but was unable to.
Removed the gauge and tried an adjustable atmosphere switch for the
8300's, but it did not work as well. I could get it to toggle both
open and closed but each time I could only do it while turning the
thumbwheel on the switch. The switch is to sensitive for this
application. There is no 10"HG switch in stock. The Westech part
number is HT170030.

WSTK.1 - Down wafers falling off shuttle blade
Found the shuttle blade was jamming the wafer into the back of the
load cassette. Tried to make adjustments and found the jam sensor
set screws were tightened to their stops. Lostened the set screws and
was able to get the shuttle to indicate a jammed condition. Adjusted
the shuttle stops for proper shuttle placement. Removed the lift cup
and disassembled due to slurry build up. Cleaned the lift cup parts
and load station with ISO. Reassembled the cup and made minor
adjustments to the lift sensors and the exit jets. Later the tool went
down for rust dripping down on the carrier. Removed the carrier and
the two seals above it. Found residual water and rust from water leak
previously in the week. Clean up the parts and reassembled the
carrier.

problem. The center of the 40 film was worn cause is unknown.
Checked the press temperature,press temp was in spec. Re-
moved the carrier and checked the down force pressure.
Found the down force was off by 10 pounds. Re calibrated
the down force. Removed and replaced the teflon button,
primary,final pads and the conditioner. Gave system back to
production to do MQC's and the polish rate and uniformity
were way out of spec. Found that the safty cam was not
adjusted properly. Adjusted the cam and gave system back to

picking Wafers from the Load Cup, when they made it there. Verified the
DI input pressure of 35 PSI. The Vacuum Gauge read 25 Inches of
Mercury, but the Vacuum Switch was not being made. Found the Vacuum
Switch to be leaking air around the Telfon Tape. Tightened the Sensor
with one full turn. Opened up FV13 a little to help with the dispense
of DI Water when the Pre-Wet is activated. Tighten both the Load
Indexer Home Switch and Shuttle Hard Stop then verified operation of
Shuttle and Load Indexer. The PM is in the Incomplete Notes File, it
only needs DI Water Samples done. The H202 Purge was already

WSTK.1 System was powered off by operator opening the rear panel.
The conditioner was bouncing around and he wanted to check
the pressure setting and opened the wrong panel. Powered
system back on and checked out the conditioner. The cond-
itioner had just been installed and was not parallel to the
pad. The front edge of the conditioner was catching on the
pad causing the erratic movement. Bent conditioner so it
was parallel. Checked pad and it looked ok. Conditioner
worked fine after adjustment. System later dropped a wafer
on the primary pad. Cleared wafer and it ran the rest of
the night w/o error.

-< carrier film problems >-
--------------------------------------------------------------------------------
The following is an action list for the Westech carrier problems we have been
having. The carrier film is degregating after only 25 wafers. The carrier
film appears to have circular pieces of film dug out or missing around the
center of the carrier.
1. Check All alignments (DONE)
all alignments are well within spec
2. Check temp and pressure of platen press (DONE)
temp was 277 with set point of 275 and down force was 191 at 30 PSI
3. Call Westech (DONE)
Talked to Tim ST Marie in Phoenix and he has never heard of this kind
of problem before. There should be no way for slurry or contaminants to get
between the wafer and the carrier. He said the 40 film is the only thing
that could cause this problem. He said the film is very temperature
sensitive and if it ever got frozen during shipment that it would no longer
be usable.
4. Order new film from Rodel (DONE)
New film is being rushed in for tomorrow via overnight delivery.
Talked to Kathy at Rodel and she told me they are having trouble with the
adhesive on the 40 film. The lots we have in the stock room is some that has
the old adhesive on it. They are rushing in some 454 grade film for us to
use. This film is similar to the 593 grade film, but has the new adhesive
that was found to be faulty.
5. Try a carrier on WSTK.2 and see if the problem will occur on a different
tool as well. ( IN PROGRESS)

--------------------------------------------------------------------------------
WSTK.1 Conditioning arm would not oscillate. Removed pad conditioner
assembly. Cleaned up some of the slurry and verified all prox-
imity switches worked. Reinstalled assembly back into system.
When the conditioner was turned on it would only lift then extend
(rotate) over the pad. It should normally then lower then start
oscillating. Found and repaired broken wire on TB29 7 in the
conditioner assembly (the conditioner terminal bd.s have Final
conditioner terminal bd designations). Arm would then lower and
still not oscillate. Found bad CB6 1 amp breaker which was in
line with the oscillation motor. Replaced CB6 with breaker taken
from WSTK.2 . Pad conditioner ran normally. We had the assembly
connected but not fully installed. When put back to normal the
arm lifted when oscillating. The mounting holes for the assembly
were causing the problem. One of the two holes is stripped, the
other is partially stripped and the only threads that grab are the
last 3 or 4. The screws are to long and bottom out leaving the
assembly slightly loose. The cam hits the top of the screw when
rotating causing the motor to shift of the extend sense switch
which then causes the arm to lift. Installed lock washer beneath
the assembly so it would snug up and fit tightly. System has been
reassmbled and the pads have been removed. Back to production
for full mqc's.

WSTK.2 Started off by adjusting the shuttle stop. Removed the load
station and cleaned up the load/shuttle/indexer area. Ran
dummys and wafers weren't being sensed in the lower middle
of the cassette. The cassette sense switch broke so I replaced
it with a new one of the same type. Noticed the shuttle tray
was cracked and coming apart where it was glued together so
that was replaced also. Tried aligning and always had one or
two slots that it wouldn't see a wafer. Rechecked home and
adjusted it slightly. Still had trouble with thru-beam.
Noticed cassette post that was moved was slightly in line with
the thru-beam sense. Moved the inner sensor to the outmost
mounting holes on the support bracket. Adjusted thru-beam
and it worked for the entire cassette. The mounting bracket is
warped so when it was tightened it went out of adjustment again
Re-aligned and it checked out good. The shuttle was bumping
the thru-beam sensor when it cycled. Cut a slot in the tray
so that it doesn't hit the sensor. WSTK.1 has a similar slot
in the tray. Started marathon run to verify transfer. Ran
2 boats so far using load/unload in manual mode.

and Bill turned up the pump pressure to ~70 psi. Continued the slurry
purge for 3 hours. removed the filter and found it completely solid with
dry slurry. Replaced the filter with a 1 micron filter. The slurry
drum was replaced with a new one, and the new slurry was cycled through
the tool. The pressure gauge is now reading 10 psi on the return.
Tool was turned over to MFG for MQC's.
WSTK.1 - Down for low polish rates.
The 1 micron filter is bypassed and polish rates were ran to see if
the filter is causing the problem.

deliver/monitor the Conditioner Down Force), to have loose/leaking
fittings on them. Tightened the fittings in question. The Process
Eng. (Matt V.), questioned whether the Carrier still had Vacuum on the
Wafer while Processing on Primary Platen. Ran the system and did not
see any problem. The Vacuum Gauge stayed right on Zero. Matt V. also
noticed the Slurry Pressure was drifting from 8 psi to 18 psi inside
the Westech. I found the same thing in WSTK.2. While looking for the
source of the problem, the Bulk Slurry went off-line. When it came
back on the Slurry Pressure was steady at 12 psi. Asked operator
to do MQC's on both Westech's. WSTK.1 still had low Uniformity.
The results are shown below: Polish Rate = 1027, Unif. = -12.36 %,
Edge Unif. = 9.65.

SUBJECT: WSTK.1 +.2 ACTION PLAN for 4/14/95
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
PLEASE FOLLOW THE ACTION PLAN, WE NEED TO STAY ON TRACK IF WE ARE TO
BE SUCCESSFUL IN IDENTIFYING ALL OUR PROBLEM AREAS. THE TOOLS (WSTK.1,
WSTK.2) NEED TO BE SEPARATED FROM THE CONSUMABLES (40FILM, PADS AND
CONDITIONER). IF YOU NEED TO VARY FROM THE PLAN PLEASE CALL ME AT
HOME, 699-4905.
WSTK.1 - After running lot B50977-39 the ending polish rate (unif)
a standard polish rate and the pilot for the NEXT LOT was
INSPEC , however the uniformity is drifting towards center
slow. Other than specific hardware issues, this has been our
primary problem for the last several weeks. THIS IS THE ONE
WE NEED TO FOCUS ON.
WSTK.2 - After shuttle replacement this tool still indicated a gimbling
problem (2 sets of apposing low/high polish rates). The tool
alignment was check ad the following adjustments were made:
pre post
Crr RU +.013 +.003"
Plt Swp +.008 +.003"
balance front neutral
WSTK.2 - After alignment the following test were conducted to isolate the
WSTK, 40 film or PAD.
2 PR with carrier 881 (40 film) 940 -10%, 5%, (gimbling)
1 PR with BE carrier (DF-200film) 920 0%, 4.5% (no gimbling)
2 PR with carrier 881 (40 film) 940 -10%, 5%, (gimbling)
1 PR with carrier 389 (40 film, 30u) 570 -8%, 13%,
* The gimbling is not due to an equipment issue all hardware has been
checked and re-checked . The gimbling effect is most likely
a false problem. The 40film could ether be swelling or collapsing
on opposing sides of the wafer.
* Nothing but the CARRIERS (carrier film type) were changed in between
these test!
STATEMENT: This last test with WSTK.2 and the fact that WSTK.1's and WSTK.2's
uniformity changes drastically with carrier changes ONLY, and the
DF200 test results point to the 40 FILM. On the last PR for WSTK.2
the rate dropped almost in half, see the WSTK.2 action plan.
The last test to be run on WSTK.2 will test the IC1000 pads for
the uniformity problem. After completion of these test we should
know PAD or carrier film.
Plan: WSTK.1:
1) Run lots, do standard post polish rate checks, if uniformity
drifts negative again please do the following:
2) Continue to build carrier with 40film lot 6y07517 on the 20u
press at 245.
3) Although it seems like we have been doing this over and over, please
replace the carrier when the uniformity goes out of spec. We are
We will work this film issue aggressively. For now, we have to use
the 40film and multiple carriers.
WSTK.2:
Done 1) Check RPC conditioner for proper operation (due to the rate drop).
Picked up a new conditioner disk for RPC2 which is in the clear
cabinet. The one on there now looked good.
Done 2) Reinstall 389, check PR.
Done 3) Install the "glue on top" pad. This is from an old IC lot which
we had good results with. Clean the bad with a nylon brush and
run several extra condition cycles.
- Check PR, if good, run 3 dummies, PR, 3 dummies PR.
If good run lots and Engineering will acquire a new batch of
IC pads.
***If the "old" pad proves to be successful on WSTK.2, go to the SR
and pull IC1000 from a lot other than DB5-xxx and install it on
WSTK.1.

WSTK.1 - Thru-beam was not sensing wafers correctly. It was decided that while
the tool was down that the peak boat modifications should be done.
That was completed and a new cassette sense micro-switch was also
installed. While trying to adjust the sensor it was discovered that
one of the screw holes were stripped out so the same was retapped for
a bigger screw. The thru-beam was then adjusted so all wafers were
being sensed. Ran a lot of wafers but kept receiving errors for a
wafer not being sensed on the carrier. Checked the vacuum switch and
inspected load cup but didn't see any thing wrong. This could have
been due me not operating the tool software properly. With some
assistance from an operator a lot was run with out any problems and
the tool was put up.

will move to pick a wafer and then hesitate about 25 sec before
registering vacuum or alarming for no wafer in the carrier. Pulled
and cleaned the load cup and reinstalled it but still had the same
problem. Tried adjusting the position of the LC with the play in the
center bolt. Suspected that the shim height on the carrier might be
to high or the carrier might some how be the problem but this didn't
make any difference either.
Ran out of time to go any further.

vacuum was achieved when pressing against the wafer and down on
the top of the carrier at the same time. Tried this with a few
wafers with the same result. Found a few spots of slurry build
up on the film. The operator replaced the carrier and a boat of
wafers were run on the DEC-CMOS5 recipe. The vacuum went up 20
Hg of water on all the wafers. None of the wafers fell off. The
arm was coming up a little jerk. There seemed to be a bit of a
suction on the wafer. The polish arm is going over the edge of
the platen. Adjusted the arm-up speed slower. Ran the rest of
the wafers without a problem. Gave the system back to MFG.

WSTK.1-Continued from C shift on monthly pm...platen run outs were good
and leveled carrier arm to 04.050in at the back and the front is at
04.052in. Tried to do sweeps and they went from left 5 to center 0
and the right went to 5 again on the primary platen. On the final
platen the deviation was even greater. Checked the carrier run out
and the it was out 0.015in tried to shim the gear box and it made
it worse so removed the shim and tried to shim the other side and
the same thing happened so I took the shim out. Check it out on
the final platen and it seemed worse than the primary platen.

WSTK.1 - Down for shuttle hitting wafers in the load elevator. Opti's were
adjusted because slot 3 and 16 were not being sensed properly. The
plunger screws for the shuttle jam load cell was completly tight on
one side and was not operating correctly. The same was adjusted.
The shuttle blade was twisted to one side so that wafers were being
placed in the cup unevenly. Straightened the blade out. The unload
elevator was floating the wafers out when it was stepped down. This
could not be adjusted out w/ the set screws so the shoe had to be
shimmed and the station realigned.

--------------------------------------------------------------------------------
WSTK.1 - Still down for some of the wafers not being seen. Tried to load a
wafer that was sensed and the shuttle went to the elevator but just
sat there. The system then errored for taking too long and trans-
port fail. Increased the pressure for the shuttle to lift and open-
ed FV14A a little. The shuttle had no more problems. Tried a number
of adjustments to the thru beam sensor and to Amp1. Most of the
wafers were seen but not all. Tried to tightened the screw, closest
to the lift, of the mount for the thru beam sensor and the hole
stripped before the screw could be tightened all the way. Tapped
the hole out and drilled the mounting holes for both screws. The
screw for the other hole is not a perfect fit to begin with. The
mount will be brought to the passdown.

WSTK.1 - Down for unload cassette will not recieve wafers...Wafers were
getting stuck at the entrance of the cassette because the
cassette was not square and not level to the exit tray. Had to
level the cassette using the two leveling set screws through
the back plate, then had to loosen the cassette assy mounting
bolts underneath the cassette area and turn the whole assy
clockwise to make it square to the exit tray. The exit tray
was too high blocking the exit jets not allowing the water
to pass by the carrier to guide the wafer into the cassette,
so that was adjusted as well.

knuckle. Both looked good. Shaft height is high at 1.182 but may not
be totally accurate because the shims are rocking. Still needs the
conditioning arm cal.

--------------------------------------------------------------------------------
WSTK.1 - Down for losing vacuum. Checked the 24 VDC from the Digital output
module for Solenoid 12 that is for the vacuum, and there wasn't any
voltage when the wafer release was highlighted. Replaced the Digital
output module and there was voltage present at wire 122 rail 1 posi-
tion 29. Then TB7 position 12 connection had to be tightened which
is for the protection diode for Solenoid 12, because it was very
loose. Also pulled the carrier off and found a nick in the fat oring
that the gimble fits into on the carrier. Ran a boat of wafers and
without any vacuum problems.
The system went down again for a change of the Primary and Secondary
pads. There are also some large wafer pieces on the bottom of the
Primary platen basin but was not able to get them out.
The system went down for not picking up from the load cup. There
was a lot of slurry buildup on the load cup. Pulled it apart and
cleaned the assembly off with scotchbrite since the white center
piece that lifts the wafer into the carrier was binding some. Ran
some wafers from the load station to the unload station and then some
using the DecCmos5 recipe. Did not receive anymore vacuum errors.
Back to production.

--------------------------------------------------------------------------------
WSTK.1 - Down for wafer missing errors and for dropping wafers as the
Polish arm lifted from the Primary pad. We found dried slurry
on the carrier. Pulled the carrier off and put on another one.
The second wafer fell off as the arm was lifting off the pad.
Checked all the fittings of the vacuum line. The swagelock
fitting at the elbow near the vacuum switch needed a little
tightening. Pulled the carrier off and placed a finger over
the hole on the shaft, and the vacuum went to 23" of mercury.
Toggled the vacuum on and off 10 times with the same result.
Put the carrier back on and the 1st wafer fell and scratched
the carrier. Replaced it with another carrier and slowed down
the raising speed of the Polish arm. Put a wafer on the carrier
and turned the vacuum on but the gauge wouldn't go beyond 3"
of mercury. Tried a few more wafers with the same result. Pulled
the carrier off and took the center piece off the back of the
carrier and replaced the large oring (viton 240). Also replaced
the thick smaller oring (viton 216) on the carrier along with
the very small oring on the gimbling button (viton 015). Ran a
boat of wafers with just loading and unloading them without a
problem. The vacuum was getting up to 20" of mercury before the
polish arm made it over to the Polish platen. Then a boat of
wafers was run using the Dec-Comos5 with a 10 second polish
time on the Primary. All the wafers ran without vacuum problem.
Put the system back up to Verify.

WSTK.1 - Down for loosing wafers off the carrier. We put some bodine oil
on the shaft of the piston for raising and lowering the Polish
arm. We also changed the pad which had over 300 wafers run on it
since the Polish arm was jerking up after about 5 seconds from
the pad when trying to come up because of the suction from the
slurry. We ran some wafers using the DEC-CMOS5 recipe and there
were no problems with the vacuum or missing wafers. The only other
problem was that some wafers were not being sensed at the load
station. After several attempts, we were able to get all the wafers
and spaces sensed. Back to production.

WSTK.1 - Down for loosing wafers on the primary pad. While running wafers to
determine the problem we caught the wafer flying out and noticed that
the vacuum (20 in/Hg) was present before the wafer was lost. It was
also noticed that there was alot of surface tension. Tried adjusting
the polish limit off the platen alittle more but there is still allot
obvious surface tension. Tried experimenting w/ speeding and slowing
the carrier speed and found that the faster the carrier was spinning
the more likely it was to drop wafers. Engineering suspected the
rotary may be leaking the same was swapped out ran more than a boat of
wafers before dropping one. Ran out of time. Also the wetting ring
was changed out.

Pulled the button off and put my finger on the hole. The vacuum
gauge was at 20. Put new button on and changed the carrier
and still will not pick up wafer at load station. Put the old carrier
back on. Noticed D.I. Load Spray was not enough to prewet wafer.
Changed the time from 2.0 to 2.3. It now picks up wafer continously.

WSTK.1 - Was down for vacuum errors at the lift cup. Found the air lines
for the lift cylinders and the lines going to the lift cup were
caught between the 2 cylinders. The upper cylinder had to be
rotated CCW to get them out. Ran 2 boats of wafers and they ran
fine. The system was put up.

WSTK.1 - Conditioner arm was not at home position.
Operator also noticed that is was skipping across table.
Removed the covers from the conditioner arm and removed
conditioner arm assembly. Found the Home position switch
pushed in and held in from slurry build-up. Replaced switch
and put everything back together. Ran 5 times with no problems.

WSTK.1 Down for not picking up the wafers from the load cup properly.
Removed load cup for inspection, found nothing. Noticed that the cup
was not coming up enough to meet the polish arm. Found nothing wrong
with the polish arm, so I added a washer/spacer under load cup
retaining bolt. This fixed problem. Production then ran tool to bring
polish rates down in order to pass.

-< WSTK.1 Polish rate problems. >-
--------------------------------------------------------------------------------
WSTK.1 - Originally down for high edge uniformity. The operator had to
replace the primary pad since only the top pad was on it. The
suba4 pad wasn't put on. After having to scotchbrite the platen
because of a lot of glue, he put on both layers of pads and ran
the MQCs. The polish rate was very low at 368. Pulled the cover
off and had to adjust the safety cam away from the major vertical
shaft. He ran 10 more warmups before the polish rate, and the
overall uniformity was the only thing out at 16.4. He ran 10 more
warmups, and the polish rate was the only data out at 871. The
overall and edge uniformities were close to being out at 14.7 and
13.3, respectively. The conditioner, carrier, and pads were new
before the MQCs. Decided to pull the primary pad and check the
down force cal. At 200 psi, the actual was 10 psi lower. Cal'd
the down force and saved it to the config. Checked the primary
platen temp on the process temp page and it was at CNTL for 90 F.
The analog data page was staying at 67 F. Checked the actual temp
and it was at 72 F. Cal'd the primary platen temp and saved it to
the config. Replaced the pad and the operator is going to run the
MQCs again.

WSTK.1 Down due to poor uniformity and polish rate. Removed pad and
installed a machine stacked IC1000 pad. Polish rate and uniformity came
back low and high. Checked down force, reballanced arm and installed
new stacked pads. Also ran with old carrier from WSTK.2 to see if it
would make a difference, it didn't make a hole lot. Tim Dyer asked
that a 20um carrier be made up. Production has yet to finish the
carrier.

-< WSTK.2 Polish arm hitting conditioner arm. >-
--------------------------------------------------------------------------------
WSTK.1 - The operator noticed that the polish arm was hitting the conditioner
arm on its way over from the clean station to the Final pad. Checked
the Clean station panel of the Pad maintenance panel, and the Primary
wafer clean time was set to 4 seconds. It was changed to 6 seconds.
Now the polish arm passes over the primary when the condition arm is
all the way over to the platen edge. Checked DCS and the Primary wafer
clean is supposed to be set at 30 seconds for the DEC-CMOS5 recipe.
The operator said that the time was changed to fix wafer vacuum
problem. So, the time was left at 6 seconds. The change was saved to
the DEC-CMOS5 recipe. Checked the Particle, Warmup, and Idle recipes,
and they were set to 30 seconds. We noticed that the carrier wasn't
going down into the clean station for wetting when using the Idle
recipe. Checked the same Clean station panel and the Carrier wetting
time and Carrier wetting interval time were set at 0. In DCS, they
are set at 10 and 120 seconds, respectively. Changed both of them and
then saved the changes to the Idle recipe. Gave the system back to
production and it passed all the MQCs.

WSTK.1 Down for breaking a wafer on the primary platen. When I came in on
the tool there was a boat of product wafers still in the unload
station and the Idle recipe loaded, also found the process timers
set for zero and the slurry pump turned off. When operator came
back into the room she stated that she had put the tool into the
idle mode. After running 10 wafers and finding nothing wrong,
changed out the both pads as per Matt Vanhanehem request. Ran 10
more wafers before turning over to production for MQC's.

Per request........
We emptied both slurry day tanks today. We then proceeded to chisel
away the Aqueous slurry from in, on top and around the day tank. Oh
ya, the containment pan was an extra special treat. Thank God for that
little propeller in the sink. It came in real handy when used as a
rheaming device to clean out the clogged drain. Once the slurry was
finally removed, we refilled the tank with water and circulated for
several minutes. We then drained this residue (which drained well now
that the "chunks" were out of the drain). Again, we filled the tank
with water and have left it circulating until new slurry is installed.
As for the metal slurry, it was a candy job compaired to the Aqueous.
Just a matter of rinsing, filling, draining, filling, etc. As with the
other tank, this one has been filled with water and is circulating.
Both tank feeds/returns were flushed in this procedure. And, the water
continues to cycle through the system as well.

37.400 | EDGE LIFT OFF TROUBLE | FABSIX::B_WESTPHAL | | Wed Jan 22 1997 19:43 | 22 |
|
CMP.C1-7 - Down for problems with lift off on the final polish. Surface
tension would not allow the polish arm to lift off the final table with
the edge lift off activated. The edge lift off was checked and we
attempted to adjust ELO position. Several variations of carrier and
platen speeds were tried and a smaller pad was also used to increase
the ELO. The problem was still there. Suspected that the arm up/down
cylinder might be bad. Replaced the same but this didn't seem to make
a difference. Tim reconfigured the tool so that it will not use an edge
lift off and made various adjustments to air flows and table & carrier
speeds. The tool seems to be operating better. Its lifting off
smoothly but some additional adjustments and verification may be
necessary tomorrow. There was also a problem with the final platen's
conditioner not sweeping out properly. The problem seemed to be with
the C. arm's up limit switch being out of adjustment. That is working
properly now.

- The lift off process we found to work on an IC1000 on the 2nd
table is: CENTER LIFT
OSCILLATING
CAR = 4, PLAT = 4
DI WATER
- If in fact the IC1000 is selected for permanent use, we may want
to try modifying the carrier vacuum holes and cutting the table
top for greater edge lift.
- Lift off on the suba-500 pad required no special requirements.
- The 2nd table conditioner was modified today and the "old" style
1X2" TBW end effector installed. 25 wafers cycled through in
CONTINUOUS mode with NO problems. A permanent, more robust end
effector will be designed in the near future.

Continued troubleshooting final platen temp problem. Checked V32 in
side heat exchanger with a meter as front screen is toggled between heat and
cool. Valve opens and closes in this mode. Suspect problem further back. Tried
to verify tc and temp readings. Inadvertently changed temp calibration on both
final and Primary platens due to our confusion on which screen we were on.
Thought we were changing set point.
Before we continue we need to recalibrate. We followed the procedures
in the book ( actually pretty straight forward, Unfortunately, actual temp would
not change to match our fluke temp display as we adjusted the analog variables.
Also noted ( as we were under the system hooking up the tc to the
fluke) that the Final platen rotary union is leaking. Next item on list.

37.404 | temp problem | LUDWIG::FINN | | Tue Jan 28 1997 18:48 | 43 |

Continued trouble shooting temp platen problem. Final temp display was now
stable, but the drift problem had mysteriously switched to the primary platen
display, huh? It exhibited the same drift that the final platen had displayed
yesterday ?? Analog inputs to opto22 were switched between channel 15 and 8,
(final and primary tc inputs). Primary channel was always dead even with
Final tc as input. Withdrew an opto22 analog brain board and and control
board.
While that was on order we removed and cleaned v32 seat. The solenoid was
working but the valve seat was always open, not allowing the heater to come to
temp setpoint. (Just like you said Brad!). Adjusted Float switch so arm will
raise and lower with water level. Ohmed out heater and it was comparable with
the other two heaters (~20 Ohms). Added Glycol.
Fired the puppy up and it heated to temp and past. Both temps were now
displayed. We did not install the boards. We put all covers back on in the
event it was temp related, but drift did not return. Returned boards to stock.
Spent the rest of the day calibrating both Primary and Finial platens, so
that set displayed readings are the same as actual temp. Also verified
Temp/pressure variables IE sample rate and band width are appropriate for
good response with minimal overshoot control. They are all within
Factory recommended limits.
Currently, the system is up and idle in wet mode/continuous with the
following temps

LOCAL PUMPING SYSTEMS PROBLEMS:
Investigated both pump chattering and stalling problems. The return line
for both pumps is coiled to improve mixing. However, this creates a
significant whirlpool in the center of the tank and allows AIR to
enter the pump input. The AIR has been causing the stalling. We put
an obstruction in the center of the tank to disturb the whirlpool. This
stopped all air from entering the pump. Immediately the pumps sounded
quieter, smoother. The tungsten pump still charters slightly. I will
order and replace this pump. When the Polishers becomes idle, we will
drain the two tanks and weld a plastic "dam" in the center.

37.410 | wall welded / leaks found | SUBPAC::LANDRY | | Wed Feb 26 1997 19:20 | 25 |
| The system was not using the Metal slurry today, so we drained the
tank, cleaned it out thouroughly, and welded a wall in the bottom of
the tank. This welded wall has stopped the whirlpool phenomina that
was exhibited prior to the weld job. Please be aware that this wall
is fairly fragile and can easily break. Please be careful when
performing any maintenance in this tank. By the way, we were unable to
find the proper welding rod to adhere this wall. But, with a bit of
A shift brainstorming, we were able to accomplish the feat!
Later in the day, the contractors hooking up the Auriga notified us of
chemical (tested as an acid) on the floor around their plumbing job.
After intense investigation, we found no chemical leak. But, it's
obvious someone along the line had a major metal slurry leak of some
kind, as the evidence of streaking, dried slurry was around the pumps,
on the poly deck and down the side of the system. We also found water
leaking in several spots on the system. One was near the unload
cassette area. We had to use RTV to seal this up. The second source
of water was in the plenum around the primary table. Much water was
found. It was cleaned up and all tubing in the general area was
checked for leaks, with none found. It may have come from the rinse
ring/plexi cover area. Please be aware, it may need to be rechecked
soon.

| Located a water leak on the primary side of the system. The tub rinse
ring's feedthrough (which penetrates the polydeck) had a fitting on the
bottom side of the feedthrough that was leaking. We have re-taped the
pipe threads and re-installed. Time will tell if this comes back.
And yes, the water to the ring is back on.
Please be aware, that this may not be the only leaking fitting under
the poly decking. Please monitor it if possible.

37.414 | TIM'S HIT LIST FOR .C1 | FABSIX::B_WESTPHAL | | Sat Mar 08 1997 20:31 | 47 |
|
CMP.C1 needs a few adjustment.
1) Loader alignment; shuttle is hitting and missing wafers
* I checked how the shuttle was picking the wafers from the cassette.
The shuttle was moving to far in so moved the hard stop out. While
running wafers I noticed that the cassette is sitting back on an angle
so that the bottom wafers hit the heel of the shuttle and the top wafers
are closer to the toe. This might be because of the little homemade
block supporting the back of the cassette. It might need to be shaved down.
While trying to adjust the hard stop I broke the cassette sense lever off
the micro switch. This happened at the end of the shift so I didn't have
time to replace it. The tool presently sits w/ the switch removed, needing
a new one and loader alignment incomplete. Sorry about that.
2) Shuttle jam sensitivity, shuttle is NOT stopping during a jam, needs
calibration
* Checked it and it was not working. I found that 1 of the 2 bolts holding
the shuttle together was loose(bottom). Tightened the same and tested it
4 or 5 times.
3) Arm down movement in AUTOMATIC is too HARD; when the arm is lowing to
the final table, it slams the wafer down, when it is unloading in the
water track it slam the wafer down.....
4) The wafer sensor in the unload cup is intermittently no sensing wafers,
please make sure the sensor head is staying clean and the N2 is keeping
keeping it purge, make sensor gain adjustments as necessary.
* I checked the load cup wafer sensor several times with a shinny tungsten
wafer, an oxide wafer and a patterned wafer. It sensed every time. The
N2 blow off also seemed to be working good.
5) Down force alarms, I'll take care of this one
6) Temp alarms, I'll take care of this also
7) W-Slurry tank dam is TOO big. Bob Gee, can you please shrink down to a
~ 2X4" damm ?
Please leave a very good pass down, I will follow up on any open issues on
Monday.
Thanks,
Tim

- Cut down the slurry tank baffles at the bottom of both
tanks to an upside down "V" and placed a top on them to
reduce the whirlpool and solids buildup. If this corrects
the problem it will be poly welded in place, so far it
looks good. Filled both tanks with water.
- Cleaned the metal slurry buildup on the wafer unload water track.
(between the two poly plates).
- Repaired an air line leak under the unload cassette.
- Cycled 50 wafers Manually thru the system with no errors.

-The Slurry tank lids need to be trimed to fit over the return
tubes.
-The 2nd table dispence arm is leaking by the end plugs, please seal
with PVC glue.
-The polisher needs a real good scrubing, especialy the unload area
and the loader cup needs to be dis-assembled and cleaned.
-The vacuum switch triger point needs to be lowered. Currently it
needs to see ~15" of vaccum to detect a wafer, causing errors just
just prior to lift off from polish table. Please lower this to
trip at ~5-10" of vacuum.

DONE -The Slurry tank lids need to be trimmed to fit over the return
tubes.
1. Lids are trimmed.
2. Drained the SC112 tank as requested by the P.E.T..
DONE -The 2nd table dispense arm is leaking by the end plugs, please seal
with PVC glue.
1. Put 4 coats of the PVC glue on. The same is drying.
2. Pads are off the tool as the P.E.T. requested. We didn't bother
to put the pads back on because we didn't know what was needed
on the primary.
DONE -The polisher needs a real good scrubbing, especially the unload area
and the loader cup needs to be disassembled and cleaned.
1. The tool was scrubbed with acetone.
2. The loader was disassembled cleaned. Adjustments were made to
the both sensors on the wafer lift assembly.
DONE -The vacuum switch trigger point needs to be lowered. Currently it
needs to see ~15" of vacuum to detect a wafer, causing errors just
just prior to lift off from polish table. Please lower this to
trip at ~5-10" of vacuum.
1. Adjusted the switch to 10".

| Ahhhhh, what a delight to once again spend the entire day with this
system! It doesn't get any better than this......To cut to the chase,
this is a brief synopsis of the day's festivities.
It took us the enitre day to finally get the alignments in. Great
learning experience for us A shifters, but not fun! After the
alignments were completed, we began to re-assemble the components that
were removed during this process. The system sits idle. It will need
new pads and a carrier, as the carrier on the system is a used one just
used to perform the final adjustments.

Not a great day for processing on the Westec - System is down pretty
hard.
Installed new pads and reinstalled the "good" carrier.
- The system would not go into wet mode
- The secondary platen would not turn
- Water or coolent started leaking out of the center of the secondary

37.432 | DF, Knife, Vacuum switch, tubing | SUBPAC::LANDRY | | Tue Jun 03 1997 20:20 | 34 |
| The system had a problem today with the air/H2O knife. The flow of air
was deemed in-adequate, dispite the 89 PSI pressure observed (when
capped off) in between the check valve and the knife. Intense trouble
shooting took place to increase the flow. ALL valves, regulator, Nozzles,
tubing were checked out and/or cleaned. NO restrictions were found other
than a couple of clogged nozzles. But, that said, the flow rate should
have been increased in the openly flowing nozzles, which was not the case.
We tried using a different piece of tubing, running straight from the back
of the system directly to the knife. The flow rate was indeed more than
adequate at this point. We then starting adding on the individual compo-
nents one by one. We eventually lost pressure (minimal) as we added on.
We found some short pieces of tubing were stretched/twisted/restricted as
well. We also noticed that the tubing we used to test with, had a bigger
inner diameter than what was on the system. Therefore, we changed over to
said tubing (with all the components hooked in line) and the flow was good.
We achieved a pressure reading of 45 PSI on a gauge (with the tubing open
ended through the nozzle) to confirm the status. With the original tubing,
we could only achieve ~35 PSI max.
Down force was also checked today. It was 10 lbs low. It was recalibrated.
The valving for the slurry/water was checked to assure now dilution was
taking place. This was checked due to the poor removal rate currently being
seen from the system.
The vacuum switch was erratic as well today. This was changed out, tested,
adjusted, and retested. A different style switch was installed per Tim D's
request. It is now functioning as should.
Also, the tubing for slurry pumps #1 & 2 was changed out. What a technicians
dream those old fashion pump heads are!
