61.6Table Stpping Problem after polish. /Step #6 value incorrectASDG::POIRIERFri Nov 10 1995 20:049
    
    CMP.A2 Table Stopping Condition:
    
    Eric Bodensieck found the cause of the problem. It seems that Step #6
    had a value of 1 sec entered for the Table. Please remember that all
    values in the step #6 screen should be zero.
    
                                                          John.
    
61.7Reworked Speedfam Carrier RingsASDG::POIRIERThu Nov 30 1995 19:4011
    
    Reworked Carrier rings from Speedfam:
    
    The rings have arrived and are in the carrier rebuild room.
    I tried working with 3 of them and all 3 had delta exposures of
    .002 or more after being tightened. D shift, see if you have
     better luck. Maybe the shims need deburring?
    
    Also, I left 16 M4 screws with lock & flat washers on the table.
    Use these fastners to on 2 of the carriers per Tim Dyer. We want to
    see if the loosening problem decreases with this set-up.

    2% Amonium Hydroxide OCP's:
    --------------------------
    
    The OCP's that monitor Amonium Hydroxide for both scrubbers have been
    repaired by Ashland. They finally traced the problem to a bad EPROM
    in the Systems Chemistry Unit down in the sub fab.
    
    The jumpers have been removed from both OnTrak electrical cabinets.
    The Scrubbers will now respond to a NH40H pressure detect from the
    OCP's. Both OCP's are now in the normal "DISP" state.

      -------------------
    
      Mitch & I could not proceed with the start-up activities due to 
      the High Purity D.I. Water being out of spec. The latest
      communication from the CFM Group is that the D.I. Water is still
      out of spec as of 3:00 p.m. Saturday. It won't be up until 7:00 Sunday
      morning at the earliest.
    
      The CFM Group contact performing the D.I. Water analysis is Diana
      Roberts. She can be paged at 508 489-6859. Mitch will be in Sunday
      morning for the latest update on the D.I. Water. If the water comes
      up, he'll call me at home and I'll come in. If any of you CMP EE
      techs are reading this message from home and want to come in on 
      Sunday, call Mitch in the fab or page him at 652.

61.14pressure plates......SUBPAC::LANDRYWed Jan 03 1996 19:4319
    The last batch of pressure plates received in from Speedfam have showed
    that the spec'd 2 um cirvature have indeed been way out.  Some have
    ranged up towards 20 um, resulting in poor uniformity.  They have been
    removed from the polishers and are being sent back to Speedfam for
    refilming.
    
    15 plates were sent back this afternoon.
    
    10 were sent back the day before.
    
    There are some more that were removed from the system late today that
    will need to go back as well.  NO SBA has been cut for these as of yet.
    
    PLEASE read Frank Krupas message about saving the data that accompanies
    the shipment of new pressure plates.  They reflect the micron
    cirvatures that we receive.

      10 Speedfam Plates arrived today. 5 were built and 5 still need 
      building. I removed 10 Speedfam Carrier Rings from the Fab6 
      Stockroom today. There are 19 left in stock.
    
    
    
61.17platesSUBPAC::LANDRYTue Jan 09 1996 19:2813
    *  I have generated an SBA to send back 5 Speedfam pressure plates.
       It's in the loop, waiting approval.  I'll bring the plates to the
       shipping receiving dock tomorrow.
    
    *  Please be sure to keep the good plates seperated from the bad.  The
       good plates should be stored in the corner, next to the rebuilding
       table.  The bad ones should be put back into the transport holders,
       then placed into the case and left next to the Vidmar cabinet.
    
    *  Opts has built all available plates/carriers for the Speedfam (8).

        Tim requested that the Speedfam Conditioning arm gimble bearing no
    longer be lubed with grease, it is to be left dry.  This is what was
    recommended by the speedfam reps.
61.19SBA's X 3 = much lugging aroundSUBPAC::LANDRYThu Jan 18 1996 12:3516
    Couple of quick updates..........
    
    *  Shipped out three Strasbaugh plates to the machine shop for repair.
       All have broken bolts or taps in the jack screw threads.
    
    *  Shipped out 5 more pressure plates to Speedfam.  These plates were
       found squirreled away in the office area.  We should be careful not
       to let this happen as we need to have 20 plates in-house at all
       times.  We only have a flow loop of 35 plates.  
    
    *  Shipped back all the replaced parts from B1's multihead that were 
       removed this week (solenoids, gauges, rotary unions, vacuum tank, 
       scrubber bracket, etc.)

       measurement gauge.  It is the original down force measurement
       gauge for the Speedfam.  If anyone knows of it's location, please
       let a first shift EE tech know, so that we may submit it for cal.
       It has a Digital calibration sticker with the # FS218.  As an FYI,
       it is NOT the gauge that is in the black case by the Speedfam

contractors working in the room activated a proximatey switch
on the slurry VMB's.  Ashland people, fortunately, were in the
slurry room as the mishap happened.  They reset the pump as
quick as humanly possible.  It's possible the major vibration

61.44adhesive backings for the RHS brushesSUBPAC::LANDRYTue Jul 30 1996 10:0822
      Greetings all,

      	As most of you know, we have a discrepancy between the the number
      of Strasbaugh scrubber brushes and the adhesive supplied with the
      brush.  Due to the 1-to-1 stocking of these two, if an adhesive is
      put down wrong, it's necessary to take another adhesive backing and
      re-apply it. This, naturally, throws off the inventory status in 
      stockroom 6. The brush vendor (Cupp Industries) supplies the backing
      with the brush.  

      	So, what is being done to offset this problem, you may ask?  A one
      time purchase of adhesive will take place.  It will be given to us
      to store in the fab (NOT the stockroom).  It will be there for emergency
      back up should you need it.  There is a minor draw-back to this buy.
      We will be receiving a roll of tape (NOT the pre-cut pieces we receive
      with the brushes).  The width of the roll will match the circumference
      of the brush.  It will be necessary to cut the roll, much like we cut
      the ID of a polish pad, to match the mounting fixture.  A small incon-
      vienience.

    At @ 06:00 this morning, we had a brief (2~3 second) hit on the DI
    system. It was long enough to put CMP.B1, and CMP-Scrub.A2 & .A3 into
    alarm for low/no DI pressure. Before we could get into the room, the DI
    system was fine again. B1 was running break ins, B2 & B3 were in wet
    idle at the time. No wafers were lost, just got the ops all charged up

61.53Particle ProblemsASDG::POIRIERThu Sep 26 1996 20:0842
    
    Particles:
    ----------
    CMP.A1.CMP.A2 & CMP.B2 are all DOWN for high particles. Kyle wrote
    new recipies for with longer rinse cycles for the Strasbaughs. The
    Particles dropped from the 4000-6000 range to the 200-300 range.
    
    This is the same approach that was taken with the Speedfams a few
    months ago when we had a similar particle problem. We are currently
    waiting for the PSS to implement an EDCO with the appended recipes
    before brining the Strasbaughs UP.
    
    
    CMP.B2 Particles:
    -----------------
    The tool and carriers were thoroughly cleaned and the pad was changed.
    The system failed MQC's for particles. 1500 - 2000 ave across 5 heads.
    All 5 carriers are being changed and a particle check will be run.
    
    2 carriers have had 2000+ wafer runs on them. The other 3 have had
    less than 1000 wafers run.
    
    
    Its not clear at this time if the particle problem with CMP.B2 and the
    particle problem with the Strasbaughs are related. The particle scans
    on the 6200 do resemble the patterns that were observed a few months
    ago when we struggled with the big particle problem. Also, adding extra
    rinse steps to the polishing recipes is having a direct cause and
    effect, much like the previous particle problem. If the other Speedfams
    start showing high particles at their next MQC's, I think its fair to 
    assume that the old particle problem is back.
    
    Eric Bodensieck has been talking to Ashland about the timimg of filter
    changes and timing of slurry barrel changes & lot #'s. He has asked
    us to try mounting a point of use slurry filter on one of the effected
    tools. I have ordered 10 micron and 5 micron filters. We will ask D
    shift to try them tonight.

    FYI, when we lost slurry to the room the blue warning light on the wall
    did not light up. When the cdu was checked the pump was in fact not
    pumping. The cdu was alarming for drum empty but Ashland informed us
    that the cdu will not stop pumping because of that. He further
    explained that the reason it did stop was due to the filter being

61.55Removal rates on the slide...SUBPAC::BJUBINVILLECMP-6 Equipment EngineeringThu Oct 03 1996 07:226
    
           We are currently seeing a decrease in removal rates on all
       of the polishers since the slurry flushing.  Some more obvious 
       than others.  This issue will be addressed in the a.m. passdown.

61.57{Power Glitch}FABSIX::J_SWENSONSat Oct 12 1996 20:058
    At approximately 1045 there was a power glitch throughout the Fab.
    No wafers were lost. Di was lost for 5-10 minutes. The tools were 
    unloaded and reset, then put to wet idle when Di was restored.
    
                      No major problems resulted.

61.58slurry supply inadequateSUBPAC::LANDRYSun Oct 13 1996 20:218
    At approximately 12:15 pm today, the slurry supply to the room dropped
    in pressure to a level that ALL the systems needed to halt processing. 
    Ashland Chemical was contacted (by pager).  Dave Spang reported to the
    call.  He arrived to find the filter clogged.  It was changed out and
    the supply was in abundance.  Manufacturing was back on line at
    approximately 1:45 PM.

61.59slurry loop flush / changeSUBPAC::LANDRYTue Oct 22 1996 20:2723
    A rough, but productive day......
    
    We arrived to find the entire room down due to excessive particles on
    all the polisher MQC's.  The particle problem increased every day
    through the week.  Slurry was again considered the culprit.  The
    previous days slurry flush was not performed properly.  They did flush
    the day tank, but did not flush the entire loop.  So, to prove that the
    slurry was the problem, we hooked up a 55 gallon drum to A1.  This drum
    had been delivered fresh this morning, a new lot as well.  The particle
    readings with this barrel were very good.  So, we had Ashland dump all
    the slurry from the day tank and the entire loop.  They then flushed
    the loop and put in the new slurry.  ALL systems passed for particle
    checks.  
    
    A note of interest......the slurry "lot" that was in the day tank and
    loop was NOT contaminated.  Rather, something within the loop had
    contaminated it.  This was proven by bringing a 55 gallon drum of the 
    same lot as the contaminated loop into the room and running directly 
    from the barrel to the normal input port (at the three way valve).  
    Particles were fine!

      As instructed, they put a 30u Omnius filter in-line.  All
      of the tools came up for flow.  Time will tell if the purge
      helped with the particles.

    --------------------------------
    Ashland called at 6:30 to say we lost slurry. As a result, two product
    wafers were broken on CMP.A2. The Ashland tech informed us that he
    removed the clogged 30 um filter and replaced it with a bag style filter.
       
    Process Engineering was called at home and messages were left to
    contact the CMP area ASAP. Due to this filter change, all CMP tools
    will need MQC's for particles before production can resume.

    The system was sucesfully purged with KOH and Slurry today. B2 just
    passed MQC's with 200 adders. System is as clean as its ever been.
    
    Note: B1 will need a slurry purge of at least 1/2 hour before MQC's are
          begun. We didn't close the valves in the valve box under the
          floor. Since B1's slurry solenoid valves are in its multihead,
          KOH has filled the lines up to the slurry valves in the
          multihead. A 1/2 hour slurry purge should clean the KOH out.

    The removal rates on B2 & B3 are now less than 1000 A. We have verified
    that the Strabaughs are no longer back filling D.I. into the house
    slurry system. We have taken the pad off B3 and will replace it with
    one from a lot other than (6DZ-JP5). We suspect that the pads might be
    the cause of the low removal rates. 
    
    FYI: We can't find a polytex pad for the 2nd table in the stockroom.
         We will only be changing the primary pad at this time.

61.74Ammonia pressure problem resolvedSUBPAC::LANDRYTue Jan 14 1997 16:2622
    
    Ammonia flow, or better yet a lack of flow, became a big issue this
    morning.  For several days/shifts, the tools in the room have been
    alarming for low ammonia flow.  Each time Ashland was contacted, they
    would call back within minutes saying everything looks good on their
    end.  But with all the tools losing pressure at the same time, the
    problem had to have one central source.  Therefore, the Ashland folks 
    decided to camp out at the system awaiting for the problem to occur.
    It didn't take to long to find the problem.  Their bulk delivery unit
    had a software command that would actuate a valve (which was either 
    purging or flushing the line) to open.  Each time this valve opened,
    the room supply would drop down below 5 PSI to the room.  When the
    valve closed, the pressure was back in seconds.  This explains why they
    were unable to first locate the problem.  By the time the call was
    placed to them, coupled with their short walk to the delivery system,
    the purge loop was activated then shut off.  So they would arrive to
    find the proper pressure and all working fine.  They have removed the
    software command from the software.  The problem has not re-occurred
    since this removal.

    lost. Ashland was here and took care of the problem.

    At approximately 11:30 this morning, we lost slurry to the room. 
    Contacted the Ashland folks.  They found that the tank had run below
    the day tanks supply tube, hence sucking up some slurry and a bunch of
    air.  They filled the tank and we were back in business.  No wafer loss
    or wafer damage was observed, thankfully.

CMP.B  - No slurry alarms on all tools.  The sensors caught some slurry bubbles 
	 when the filter was being changed.  Corrected the situation and 
	 cleared the alarms. 



61.81Pad's Glazing on A and B ToolsFABSIX::J_SWENSONSat Mar 29 1997 19:3121
     PAD GLAZING
     -----------
    
    
                  Today there was incidents of pad glazing on cmp.a2,
                  cmp.b2 and cmp.b3.
                  
                  It seems that there has been an increase of glazing
                  which requires extra conditioning to prevent.
    
                  Looks like we may have some hard pads within our stock.
    
                  The glazing on B2 acually caused the tool to vibrate
                  during polish, the pad was then reconditioned which
                  brought the pad back.
    
                  Will need to keep an eye out for future glazing

	CMP.A1    Has new pad (not wet), new conditioner, and
		  there are two new carriers in the room ready
		  to be put on tool.


	CMP.A2    Failed 24 hr MQC's. Took off pads and conditioner
		  Put on new conditioner, but left pad off so I 
		  could put the tool in wet idle to keep the carriers 
		  and brushes wet. The carriers only have about 270 
		  wafers on them.

          Lost slurry from Systems Chemistry unit.  Ashland
      tried swapping pumps because the one that was on-line
      sounded funny.  After the swap, we still has little pressure.
      The filters were checked and they were clogged.  They replaced
      the filter(s) and we were good to go.

     - The slurry system was purged today at approximately 1430.
    
     - A1,A2 and B3 were put on barrels and run.
    
     - At 1710 the purge was completed and all tools put back to house
       system.
    
     - As of 1930 all tools have been running without issue.

* NOTE - The recirculation motor for the metal slurry distribution unit was 
changed out with a new part as requested by engineering.  The old pump sets in
the metals room sink needing to be Decontaminated and we need a decon sticker.
