Subject: CMP-V SERIAL #47 SOURCE INSPECTION REPORT
Summary:
Digital arrived on the morning of 12/9/96 to perform a customer source
inspection for serial number 47. It was our immediate impression that the
tool was not ready for the source inspection as was the case with serial
number 24's source inspection. The tool was not fully configured or tested,
see configuration issues listed below. It is the customer's expectation that
prior to customer arrival the polisher has been: 1) FULLY tested by SpeedFam
prior to our arrival; 2) Operating with the latest released version of software
3) The customer's recipe has been robust tested using all aspects of the
software including activating the alarms. In addition our local FSE arrived
several days ahead of us with intention of performing a pre-source inspection
to ensure the system's readiness prior to customer arrival. The FSE was not
able to perform the required testing. As a result of the above not being
completed, the polisher errored for "low down force" on second table during
processing of our first wafers. The actual problem was due to head-1 not
lowering in sufficient time. If the polisher had been tested by SpeedFam and
again by the FSE, this would not have occurred on the customer's time. One
day was lost due to this which should have been avoided. Speedfam needs
to improve their pre-source inspection testing to come up to industry standards.
Once the software was updated, the recipes corrected, and the head-1
problem was corrected, the source acceptance ran without ANY issues. The
500 wafer mechanical marathon ran with out any alarms/errors. Following the
mechanical portion the process acceptance testing began. Speedfam configured
the system for process testing with old generic carriers/plates. As a result
10 wafers and ~2 hours were lost trouble-shooting the problem. After locating
acceptable carriers/plates, testing resumed. A few small offset and ID/OD
adjustments were made and the 50 test wafers were committed. The process
results were acceptable.
On a positive note the system ran without ANY issues once the head-1
problem was corrected. It was also refreshing to have an oxide measurement
system in the same room as the testing was performed and to be the first
customer to use the new spin-rinse dryer in the room(even though we had to
program it).
OPEN ISSUES:
Configuration Issues:
1. A/B boxes not installed
2. Remote terminal and key board not located
3. SECS-II not installed. Installation will require automation frame
separation, replacement of bulkhead panel and installation of
hardware. Due to any possible disturbances, Digital is requesting
an additional 100 wafers to be cycled through the tool after the
SECS-II work is completed..
4. Robot pendent not located
5. Chiller serial number ___________
6. New style door not installed.
Mechanical Issues:
1. Leak at top of fluids manifold
2. Leak near vacuum tank
3. Leak detect not enabled
4. Down force calibrated with load cell and aluminum wafer directly
contacting the carrier film. This procedure causes a 15-20 micron
dip In the carrier films. Procedure needs improvement.
Software Issues:
1. Most current released version not installed, changed from 494a to
494e.
PRODUCTION MANGER WILL SET-UP PROCEDURE WITH SOFTWARE GROUP TO
ENSURE THE FLOOR HAS THE LATEST RELEASE OF SOFTWARE.
2. Carrier pressure alarm configuration screen is not configurable for
primary and 2nd table to correspond with high and low end pressure
settings. Second table continues to error with low down force
settings of 80lbs with a 10% error limit. Need one screen for low
end and one for high end conditions.
WILL BE AVAILABLE IN SPEED495.
Process Issues:
1. System configured with old generic carriers/plates for process
testing. Why was the process portion not planned with new
customer carriers/plates?
SPEEDFAM FINDS IT VERY DIFFICULT TO USE CUSTOMERS' PLATES
BECAUSE THEY HAVE TO BE DIS-ASSEMBLED AND RE-ASSEMBLED PRIOR
TO SHIPPING WITH THE TOOL. TO CORRECT THIS ISSUE THEY WILL
HAVE AT LEAST 5 "NEW" CARRIERS ALWAYS BUILT AND READY FOR
CUSTOMER USE ON THE PRODUCTION FLOOR.
Process Results:
Parameter Spec Actual
============== ======= ========================
Avg removal rate >=2000 3729
Avg %Std.Dev. <=5.0 4.26
Max %Std.Dev <=8.0 8.1 (6.73 without 1st run)
Max HTHNU <=5.0 7.88 (4.59 without 1st run)
Throughput >35 wafers/hr 36
These results are consistent with those observed at previous source inspections
and the system is deemed acceptable pending the closure of the open issues
listed in this report. Speedfam has agreed, and assured us the open issue WILL
be closed prior to shipping. We will call to confirm on 12/18/96. The tool
will ship on 12/19 and arrive here on 12/23....Merry Christmass!
OTHER ISSUES AND ACCOMPLISHMENTS DURING THE VISIT AT SPEEDFAM:
o Signed-up Digital for Beta testing of Speedfam oxide endpoint system. We
will be the 3rd beta site and are scheduled to receive the system 3/1/97.
o Signed-up Digital for the 1st beta test of Speedfam W-Endpoint system.
Should come with the Auriga tool#65 in 2/97. Looked at their UEP system.
They've run into repeatability issues with this carrier current monitoring
system. Also heard some negative feedback on Luxitron system from AMD.
o Met with the engineering design manager to go over CESs for Auriga. These
included requirements and some design ideas for the 2nd platen pad
conditioner and slurry pump set-up.
o Met with Randy Smith, Software Engineer, we Demo the SECSII software package
and reviewed the VIRTUAL CONTROLLER design requirements. Both systems Look good,
we will need to work with CIM to get Digital's end of the interface software
working.
o Looked at their second platen wafer-loss detect system. Looks promising,
however, it is too big and needs to be miniaturized.
o Held a meeting with the Reliability Manager, the Filed Service manager,
Reliability Engineer, NE Field Service Manager, and the NE Sales Manager to
discus CMP.B1 head-3 stalling problem. Although Speedfam is working on a
long term rotation failure fix, I requested an immediate plan of action. It
was decide that an "old style" motor would be located, installed on head-3
and tested at 400lbs. The initial test failed, the motors's resolver
was than rotated 30 degrees and re-installed. Head-3 ran with out a
stall at 400lbs. A long term motor stalling plan is in progress at Phoenix,
due some time in January. This fix will apply to ALL CMP.B tools. It most
likely will include all new infranors, and some software constant changes.
o Meet with Bill Spencer, Carrier Films Manager, in Phoenix on Monday and
finalized the DIGITAL carrier list. There is only one plate mia. The updated
master list will be generated and put in carrier build room. We own and can
account for 61 plates, plus 20 new plates shipping with B4, for a total of
81 plates.
o Meet with Mike Slepekes, training manager, to discuss plan for Auriga
training. The first available class for customers is not until late March.
Once a schedule is finalized, it will be sent to Digital training dept.

Install status for 1/13/97
KSI got alot of things done today. They are waiting
for an insert for the N2 line which should be done by this
afternoon. They are "drawing" up plans to construct a safety
barrier with unistrut to go around the plumbing. They are
waiting for a manifold set-up for in the fluids cabinet and
in the VMB to be assembled. They are planning on having
everything done for tomorrow's sign-off.
On our end... With SF Reps, the chiller cables were run
from the tool to the chiller and connected and the light
tower was re-mounted on top of the tool.
All of the facilities are ready at the valves on the wall
and we'll turn them on tomorrow to check for leaks.
The red CMP.B4 label was ordered for the front.

KSI didn't have the parts in-house for the slurry manifolds
so we're going to have to wait another day on that. The did however
construct the unistrut frame to go around the plumbing but the
floor panels weren't ready so don't lean on it.
The chiller was filled with 50/50 glycol/DI. The system wasn't
powered up so we'll top it off when it does tomorrow. The PCW, DI,
N2, CDA, PV and RAW water were turned on. There was a tee fitting
that was used at the factory to flush the system of DI which we removed.
Rich and Dave installed the vent covers and other panels that need
to be installed after shipping.

Tool was powered up in the a.m. with one minor
issue. The Infranor for the conditioner suffered
electrical death during transit. That was replaced
with a new one.
The chiller was powered up and topped off. It's
now flowing fine throughout the tool lines.
The vacuum pump was pulled apart and cleaned out.
the reed valves were replaced.
Right now there is an issue with the monitor in front
not coming on. There is a issue with the SF A/B box inside
the tool. SF Reps are looking into it now. There is a
15 pin female to female adapter that is no where to be found
so we might have to do a road trip to Radio Shack tomorrow.
This connector is needed to connect the remote monitor to
the tool.
There is no door interlock installed on the door to the
electrical cabinet. This was an option for the customer. We
have asked SF to install one.

Speedfam Reps started marathon and after 180 wafers
cassette "A" mapper errored for cross slotting. Reps
worked on problem for about 4 hours and problem went away.
Started marathon again and after 100 wafers, the same problem
occured. Reps determined problem is with the encoder for
cassette "A". They have ordered a new tilt assy. and expect it
in tonite (Sunday nite). Kevin will pick it up and bring it in.

CMP.B4 - We are currently 350 wafers into the 500 wafer marathon. the 1st
marathon was stopped at the ~200 mark for a bad encoder on the
A tilt module. Once the mechanical acceptance marathon is complete,
we we have several more items to address before releasing to Pro Eng.
1. Down force will be recalibrated based on the high head-head range,
seen in the data below. A repeat MQC will be performed.
2. Slurry manifold needs to be built and installed.
3. The Mega slurry system needs to be released in order to supply bulk
slurry to B4.
4. The SECS-II kit installation needs to be completed.
5. Local and global slurry detection needs to be installed and
tested.

The tool completed the 500 wafer marathon without a single
ASSIST. Rich is going to check the downforce on all (5) heads.
After they are checked, (5) MQC wafers will be run to check
the removal rate and uniformity. Jim Sadin will be running
the MQC's and will post the MQC data in CMP.B4 NOTES topic.

which got me to where I needed to be. Got tool initalized and we
are on the way to finding just where the leak is coming from.
Did find ONE drop hanging from one of the drain tube ports under the
scrubber. That was at the beginning of the investigation. Found a
significant leak around the left drain port in the scrubber bay.
Did some more looking and found that the leak appears to be under the
scrub wafer pedestal. A good amount of water was foound in the far end

masterflex tubing we normally use and put a new 10 micron filter in.
Noticed that the slurry flow to table #2 was low but ran out of time.
the slurry flow still needs to be calibrated. The support that holds
the return pipe for the metal slurry broke off. Tried to polyweld it
several times using different rods but couldn't get a good weld. This
could be due to the different types of materials. Bolted the bracket
to the upper lip of the tank w/ ss screws. I will replace them later
when I find some Teflon screws.

added slurry. Ran slurry in manual to remove air bubbles, aok since.
System errored for vacuum. Found double load on all five heads.
Ran again and watched, found that wafers were not being blown off the
carriers prior to loading the next 5 wafers. We ran and monitored i/o and
found vacuum turning off prior to blow off but the main n2 blow off
solenoid (i/o 14) for N2 was not being told to turn on. Check fuse and
opto 22 aok. Problem was loose ribbon cable. Tested aok.

- Cassette B, Robot not picking up the 15th wafer and hitting

Adjusted the tilt front to back. Ran 100 verification wafers
with no problem.
*** Need to keep an eye on Cassette B, It seemed very strange
that it would not pick up only the 15th wafer and every
wafer prior was o.k. and every wafer after the end efector
would just nick the wafers. Tried several different
cassettes and the results were the same.

CMP.B4 - Never went down in the system but the tool was coming up with strange
errors. When production tried to run some tests for engineering they
got various errors. Soft booted the tool and while it was homing I
received a vacuum error. The gauges on either side of the filter had
different readings so I changed the vacuum filter. The gauges still
were still reading 4lbs. Different so I don't trust the gauges.
Hard booted the tool without any errors and ran 5 wafers on the
IO_MQC recipe without any trouble. Logged an assist.

The moisture alarm was going off after lunch. Traced
problem to the sensor under the scrubber area. Water is
dripping from the same area as just after the install.
The water is wiped up but we will monitor the leak. The

Mapper Error:
------------
Tilt Mechanisim #1 repeatedly created mapper errors this morning.
We sucessfully mapped a full cassette of wafers with no problem.
We then sucessfully mapped using 5 different full cassettes.
Changing cassettes didn't seem to make a difference. The
mapper error reoccured everytime there were 15 wafers in a
cassette. It wouldn't with more than 20 wafers, or less than 10.
It repeatedly failed with 10 to 20 wafers in ANY cassette.
We noticed that the 3 spring loaded leveling screws under the tilt
mechanisim platform looked different. The springs on the 2 screws
facing the front of the automation frame were fully compressed
while the spring on the 1 screw that faces the rear of the automation
frame was barely compressed. This condition requires the weight of 10 or
more wafers to compress the rear spring to the point where the
Robot will sucessfully map the cassette.
We're theorizing that the tilt mechanisim platform needs to be readjusted
to a level position while maintaining equal compression on the 3 spring
loaded leveling screws.
We didn't want to change the tilt mechanisim adjustment since none
of us knew how to teach the new style robot new posistions.
We managed to get through the shift by asking gwen to load more than
10 wafers into a cassette on each run. She then selected to polish
wafers from the appropriate slots.
Crash at 7:00 P.M. :
------------------
The system broke 2 product wafers at 7:00. We're not sure when the
breakage occured because there were no error messages or audible
alarms.
This was the condition the tool was in when the breakage
was first noticed by operations:
1) Head #4 down on table, all other heads up.
2) Wafer missing out of head #4. Wafer broken on pad with chips
under head #3.
3) Wafer in head #3 scratched and cracked in half but still in
carrier.
4) Blue stripe across bottom of touch screen with words " ENDING RUN".
5) The tool was running the IO_ILD1 recipe at the time of the
crash. The tool was 10 seconds into segment #7. Gwen informed
us that we were half was thru the 20 sec rinse at 313lbs of
down force and that she had been running this recipe all day
no problems.
We're currenly cleaning up the mess and removing the carriers
from the tool. We'll be handing over the troubleshooting and
verification to "B" Shift shortly.
P.S Thanks gwen for assisting us in the data collection.

We had some problems with the load station.
Load 1 kept erroring for cross-slotted wafers.
We leveled the load platform and were able to
clear this problem.
Then a problem occured with Load 2. The robot
is going in to far to get the wafer and putting
it the pre-aligner off center. The pre-aligner
doesn't know it has a wafer and when the fingers
come down to get the wafer it can't pick it up.
Didn't have the time to make necessary adjustments.

| 23.52 | crash, program edited | SUBPAC::LANDRY | | Mon Apr 14 1997 20:46 | 30 |
| Well, another rough ride today with this system......
Several nuances from the previous day were taken care of early
in the day. See the previous note for details. After all items
were fixed, we began to perform the breakin of the pad that never
quite got done the previous day. All the respective "BREAK IN"
recipes ran flawlessly. We turned the system over to Opts for
MQC's. The very first run, the system crashed. A wafer got away
from Head #1, taking carrier #5 all with it. Cleaned up the mess.
RE-checked head to cup alignment, which we confirmed as good. Down
force was check on all heads. All were within 1 pound of spec except
for head #1, which was 3 pounds out. Regardless, all were tweaked
to tighten things up a bit (seeing we were there anyway).
After all the above checks were completed, we scrutinized the IO_MQC
program for discrepencies. We found that the post polish rinse steps
showed that the program was delivering 40 second on rinse water with
300+ pounds down force. The program was adjusted (segment 7 was
changed) for the down force to change in segment 7 from 313 pound
down force, to 80 pounds down force. Therefore, segment 6 is 20
seconds DI at 377 pounds, and segment 7 at 20 second DI at 80 pounds
down force.
MQC's to be run soon. Unfortunately, a contractor messed up on some
plumbing lines, which caused the slurry in the tank to get diluted.
We are currently in hold (ON B4 ONLY, AS IT'S THE ONLY SYSTEM UTILIZING
THIS SLURRY), awaiting word from Ashland Chemical that the system is
ready to run.

CMP.B4- Down for "carriers not rotating" error, the screen being locked up and
scratches. There were 2 wafers on carrier #1 and wafer #1 was missing
from unload cup #1. Obviously carrier # 1 failed to blow the wafer off
from the previous run. We had the same problem on CMP.B1 last week.
Recovered wafers, rebooted the tool and observed tool while production
ran 10 warm ups and 5 MQC wafers. Tool went down later for scratches.
Cleaned the conditioner and process area, changed both pads and
carriers #1 & #2. Dumped the index table, pulled the cups and wiped it

CMP.B4- The tool never went down in the system but it was not blowing the wafer
off carrier #2 very well. It was noticed that Air was bubbling out
between the secondary housing and the gimbal assembly. Took the
carrier apart and found that the carrier plate was not tight against
the secondary housing even though the bolts were torqued to 8 lbs.
With process engineering's permission the bolts were tweaked a little
to pull the plate against the housing. This corrected the condition
and the tool was returned to engineering.

* Note Concerning CMP.B4 from Bruce Tower- CMP.B1 was put to external to begin
decontamination and preparation for shipment back to SPEEDFAM. Engineering
would like to keep CMP.B4 as long as the other tools are running okay. In the
event that production should need the tool Bruce requested that slurry pumps 1
& 2 be hooked up to a barrel of SC112 (which is at the tool). The proper
tubing to hook the barrel up to slurry pump #1 & #2 solenoids are on top of the
barrel. This is because the MEGA SLURRY SYSTEM's percent solids is at 18%.
An MQC must be done to verify there is no problems w/ the slurry.

Gwen will let Brad know for sure when that happens. We will not be
Testing SS25 at 18% until Tuesday. So, we need to hook the SC112
drum up to the system and turn over to production for the rest of the
weekend. Please keep a close eye on the barrell to make sure there is
enough before Ops starts each lot. The system was fully qualified
at 12.8% solids before we started the other slurry tests. Process Eng
has also sent out a note stating such. Of course the Ops folks will
run MQC's again to make sure of system integrity before any product is
run through it. Any questions or concerns give me a call at home.

back to wafer loss board. When we jumpered out wafer loss, no errors occurred.
Frequency of error increased to every run and error was finally captured by

| Matt should be able to complete the SS25 (18%) test lot today. When
his lot is complete we need to remove the barrel and hook the system
back up to the mega system. Please keep the barrel of SS25 in the room.
The lot that we ran Saturday will be back for ILD3 later this week or
early next and we'll need to hook the ss25 back up.

Tool failed for wafer detect system. Found #3 and #5
wafer loss sensors tripped on the board. The sensors
were not hitting anything, they just needed re-calibration.

| 23.79 | Unload flipper box sealed & adjusted / Srubber station leak / high particles | ASDG::POIRIER | | Fri May 09 1997 20:29 | 38 |
|
Unload Flipper to Unload Cup Alignment:
--------------------------------------
The unload flipper box cover was removed and sealed with rtv.
After the box was closed up, the flipper fingers were moved which
caused a wafer pick-up misalignment. The flipper to cup and flipper
to scrub aligments were reset. A 15 wafer verification run was
completed with no further problems.
Scrub Station leak:
------------------
The leak under the scrub station was sealed with RTV this afternoon.
The RTV cured for 2 hours before the water was turned back on.
We just checked it and its now leaking about 2 inches away from the
sealed area. It looks like another application of RTV will do the job.
Put a bead of RTV around the cut out under the scrubber area.
(A green air line is located in the center of the cut out)
High Particles:
--------------
The system went down at 6:30 P.M. for Pad step height and HIGH
PARTICLES.
1) We noticed a small quantity of rust particles around the
inside edge of the pad. A closer inspection revealed rust comming out
of the center of the platen. (At the junction of center ring and the
main platen) We cleaned with a scotch pad and rinsed with DI water.
2) The Di water pressure was at the low end of spec. 20 psi
The spec is 20 -30. It was increased to 29 psi.
The gage on the wall is reads zero.
B2 = 27 psi
B3 = 30 psi

| 23.82 | safety upgrade | SUBPAC::CMP | | Tue May 13 1997 20:25 | 3 |
| Today we installed a safety lock for the multi-head. To use this
device, you place it under the multi-head lock lever when in the locked
position. This prevents the multi-head from moving.

Trouble shot 24vdc solenoid while disconecting and connecting
lines and testing the cda loop problem disapeared and tool was
returned.
Robot missing wafers intermittently on cassette B.
Tightened tilt plate screw and retaught robot pos for cassette B
and also noticed that the robot was not placeing the wafer correctly
at the alighn station so retaught that position.
Everything tested fine so returned tool back to production.

CMP.B4 - Down for high particles. Particles were over 1300 for each head.
Ashland chemicals was contacted and a filter change was done.
Particles came in under 300 per head.

| The tool failed MQC's for high particles. We suspect the filter
for the mega system needs to be changed, this took care of the
particle issue yesterday. Called 3 different Ashland beeper #'s and
left a message at 6112, with no response back. Will have "B"

found severe scratching on five product wafers run on CMP.B4. Tried
to isolate the cause by running wafers only on the primary table, and
then only on the secondary table. Neither produced scratches. Cleaned
up all the carriers and the conditioner. Replaced the scrub station
brushes as they looked a bit dirty/worn. Ran a set of mqc wafers and
particles came out great (in spec, no scratches). Turned tool back over
to production.

| 23.92 | Infranor, PM and unload flipper issue | SUBPAC::BJUBINVILLE | CMP Equipment Engineering | Wed May 28 1997 08:28 | 33 |
|
Slurry barrel was getting low so it was replaced.
During the run, it appeared that the unload flipper
had the 3rd wafer of the run and some how dropped it
in the paddle track. The tool was alarming when the
operator noticed that the paddle was trying to go home
with the product wafer in its way and the tool was alarming
for wafer not present at unload. The tool was EMO'ed
while it was still polishing. All of the load and unload
wafers were removed and the tool powered back-up. Tool
alarmed for heads #2, #4 and #5 not rotating. All (3)
infranors had L2 lit on them. Multihead transport was
also red with L2 lit up. After another reboot, only
#4 wasn't rotating. The infranor was replaced and the
tool powered back up. Now only @2, #5 and MHTA where lit
with L2. After another powerdown, just #5 rotation was
lit with L2. There were no more in stock. Rich was called
and is trying to get (3) in here ASAP. OPS gave us the
tool for the week-late monthly. All of the PM's were
completed for the week on the tool. Head #5 was taken
off line and the carrier in staying wet. A WARNING will
will be placed on tool. The leak was investigated but still
no source found.
The unload flipper sensor block was loose and needed to
be tightened. Wafers were run for VERIFY. Tool ready for
break-ins.

| Spoke with Ashland this morning. They felt the mega slurry system
should be clean after multiple days of flushing it out. Removed barrel
and ran MQC's hooked to mega system. Particles still high. "Large"
around 300 and total 1100 on 3 out of 4 heads. Hooked barrel back up but
have had problems getting an MQC done due to scrubber issues. Gwen
should be doing one now. The infranors were ordered and should be here
"around" 11:30 tonight. Plan is to run 4 heads until the infranor's
show up.
