Air leak SV9.  Reason slow in rinsing up or maybe low on DI?

>>> 'sink6' problem from phillip -- Fri Jan 19 07:01:12 1990 <<<

Per Carl's report:
 SV9 - no trouble found.
 SV11- replaced faulty section of air line.
sink6 is up.

>>> 'sink6' problem from murray -- Wed Jan 24 15:20:20 1990 <<<

Resistivity meter will not go above 4 and fluctuates around 1-2 with 
cassette in tank 6.  Soaking in piranha and rinsing 2 mins in tanks 4 and
5 doesn't help.  However, resistivity will go above 17 with nothing in 
tank 6 indicating that meter is not at fault.  M. Murray and T. Wilson
suspected that cassette might have been dropped or contaminated.  We placed
dirty cassette on counter opposite sink6 clearly labelled not to use.  With
new cassette from drawer and new wafer, resistivity tops off at 17.1 so we
are leaving new cassette in sink6.

Problem: contaminated cassette at sink6

Forgot to mention this after I used sink.  Got full plenum lockout
alarm 4 times while using sink.  Would alarm and shut off rinse.
After rinse off, if I would hit ack. button it would go off and
sink work again.  Does short alarms like this mean the drain is
weak or maybe the sensor is too tight?

Got that short full plenum lockout alarm twice.  Actually resets
itself after a few seconds.  Not only me, Michael Judy had it
happen to him also this morning.

Sink 6 still suffering from full plenum lockout syndrome. Alarm sounded
for about 10 seconds and then shut off without my pressing silence key.
No further problems, so finished wafer run.

>>> 'sink6' problem from galewski -- Tue Feb 20 12:19:10 1990 <<<

plenum lockout alarm hit twice again.  resets almost right away.

>>> 'sink6' problem from bob -- Tue Feb 20 14:35:15 1990 <<<

The full plenum lockout on sink6 seem to be caused by the aquamatic
not fully opening on demand. The presure regulators that hold off
this valve (40psi) and the one that supplies the opening force
60 psi have been reset to:
hold off=40 psi
open    =65 psi
The sink is now draining at normal rates.
A remaining problem with this sink is a plenum leak apparently in
the lower seam of the sink by the Herman-Miller wall. repairing
this will be added to Phill's joblist.

I tried to immerse it in the parahna for whole night to remove the mess
but it is in vain. The resistivity is still in between 9 to 10 Mohm.

Problem: A user reported that he suspected one of the sink6 cassette
         had been contaminated.
Solution: Sink6- plus ALL the cassettes and handles, including the
          new (opaque) cassettes and handles for 2" wafers- have
          been RCA 1&2 cleaned.  After the clean was complete, the
          cassettes and handles were overflow-rinsed for 30 minutes.
          Sink6 is UP.

Problem: User reports full plenum lockout.

Solution: Drain valve and drain rate were checked and are about
normal for a sink. Phill will check the fill rate adjustments
on thenrinse tanks and make sure they do not exceed the sink
drain capacity. sink6 is up.

We have no DI water flow.  I didn't check the flow before putting
my wafers in the sink6 piranha.  When I removed them and put them
in first quench, I noted that the flow was very low.  By the time 
I reached resistivity, I had no flow.  I am disabling the sink for
the time being, leaving two cassettes full of wafers 
in still quench water.  I'll check back in two hours to see if we
then have DI flow.  Since the wafers are still at very low resis-
tivity (the highest reading I got was .21 Mohm-cm), I'm not going
to put them in the sink6 dryer.  If I do anything else, I'll con-
taminate the cassettes (if for instance, I used the sink8 dryer).
If there's still no flow in sink6 two hours from now, I will leave
the wafers in water overnight.  If I have to do it, it will be 
labeled, and I ask that if someone else comes upon them before I do
tomorrow morning, that the wafers be put through piranha again, 
quenched and rinsed to > 14 Mohm-cm, dried and only then placed back
in the blue box that I'll leave near sink6.

Bill Tang was good enough to let me go ahead of him on Tylan11; unfor-
tunately this had to happen and I couldn't use it.  

Is there any way I could have checked beforehand so
that I at least didn't have wafers stuck in the water for hours?  

RLA

>>> 'sink6' problem from alley -- Thu Apr 19 22:33:49 1990 <<<

Not actually a problem to report this time:  everything worked fine 
and there was sufficient water, only I missed my chance to get into 
tylan11.  I suppose the only question remaining is how I could have
told beforehand that this would happen.  I think I vaguely remember 
being told something I could check, but I've forgotten what.  AND
EVEN THEN, RUNNING OUT OF WATER WOULD HAVE BEEN A PROBLEM.

>>> 'sink6' problem from alley -- Sat Apr 21 19:09:02 1990 <<<

the sink isn't down or anything like that, but after the two sink6 cassettes
of wafers were taken from the dryer over to the furnace aisle, I had a 
problem which may have contaminated the cassettes.  This is why there are
two 4" sink6 cassettes out in plastic wrap, waiting to be cleaned.  The 
wafers were to be loaded into tylan11.  While doing so, and with the 
tylan11 sled out, the polysilicon on the sled and boats spalled and I got
polysilicon particles all over the sink6 cassettes (and my wafers) which
were below.  I don't know if the usual practice is to rinse off the cassettes
in sink6 or to put them through a contamination clean, so I was conservative.
See tylan11 entry.
