Subject: Wet Bench Retraining
Message-ID: <3AEF7BCE.FEC17FF7@snf.stanford.edu>

Wet Bench Users (wbdiff, wbsilicide, wbnonmetal, wbgeneral):

I am sure most of you would agree that things have been getting a bit
out of control at the wet benches.  Many people are not certain of the
proper procedures for handling chemicals, cassettes, and wafers.  And a
few people don't seem to be exercising common courtesy.

There are going to be a number of changes to the wet benches, in terms
of operating procedures, policies, and equipment (see below).  These
changes we hope will make the wet benches both safer and easier to use.

The first thing we would like to do is to make sure everyone is starting
from the same, basic understanding of how to use these benches.  New
operating procedures have been written for these wet benches.  Everyone
currently qualified on these wet benches will be required to read these
operating procedures and take written tests to indicate their
understanding of the procedures.  This policy is effective immediately.
There will be a one month grace period in which currently qualified
users will be able to remain qualified.  After May 31, anyone who has
not turned in and passed the written test will lose their qualification.

These tests will be available in Uli and Henry's office, CIS room 146,
located next to the CIS Xerox/FAX room, under the stairs.

A final word about the tests:  there really is nothing to prevent you
from sharing answers -- but please don't.  The purpose of these tests is
not to screen people from working at these benches, but to educate
everyone on their proper and safe use.  Please abide by the Stanford
Honor Code (even if you are from Cal.)  By submitting your tests you are
saying that you understand and will follow these procedures -- and
everyone will be expected to enforce them.

Some of the other changes that are coming up:
1.  The Nanostrip hot pot will be converted back to a sulfuric/peroxide
hot pot.  (We haven't given up on Nanostrip, but just put it aside until
we understand it better.)  The announcement is imminent.
2.  We are in the process of reprogramming to controllers so that hot
pots can be aspirated at a higher temperature.  This also requires
checking the facilities to make sure we can handle this.  Acid changes
will be much faster once this is done.
3.  There is serious discussion about gloves, safety gear and general
ergonomics.  If you have any suggestions or ideas, the SNF staff would
appreciate hearing them.

If you have any questions regarding this requirement, or any of the
specific wet bench procedures, don't hesitate to contact the SNF staff.

Tony, and all others who use the ctb at temps above 60C

The water will evaporate, despite the foam covering.  This morning I found the 
bath completely empty and the motor making a rather nasty sound.  This is very 
bad. This can destroy the heating elements, and the recirculation motor.  
Luckily, this did not happen this morning.  I refilled the bath and it seems to 
be working ok. Tony, be aware that your process was not at the desired temp for 
an unknown period of time.  All users need to be aware that the water level 
needs to be monitored on a fairly frequent basis, especially when running at 
higher temps. For temps above 80C, the bath should be checked 2-3 times a day, 
and refilled as needed.  Thanks in advance for your cooperation.

Does anyone know where to buy it ?

L.P. Glassblowing of Santa Clara (408 988-7561) provides most of the
quartzware in the fab. They can rebuild the broken device or construct a
new one using the old item as a model. Stefan, come and see me with the
broken pieces and we will get you going again.

Subject: Rant!
Message-ID: <3B0D4655.EB6804B6@snf.stanford.edu>

I need to get this off my chest:

1.  Please don't make policy changes!  If something isn't to your
liking, ask one of the Staff...  The KOH quartzware was found outside
its clean roll-around storage box and relabelled "Gold Contaminated."
Quartzware is made out of quartz (duh) and is darned expensive and
darned hard to work with (I just returned from Turkey, where I learned
that processing of quartz tiles was historically given over to the
elderly because the life expectancy of quartz workers was so low).  If
you need gold-contaminated glassware, use pyrex, which is a heck of a
lot cheaper (yes, it contains sodium, but if you are working with
gold-contaminated materials, it shouldn't matter -- contact Staff about
ordering it.)  A great debt of appreciation to Eric, who decontaminated
the quartzware.

2.  Please clean up after yourselves!  Put away clean, dry glassware
before placing wet glassware on the table.  This will provide more room
to work.  If glassware is broken, throw it away in the "Sharps" box
(more on this later.)  Try to minimize the amount of personalized
glassware at this station -- everything is considered gold-contaminated
here (except for stuff stored inside the "Clean" roll-around box.)
Heck, I've no qualms about using someone else's labeled glassware if I
need a container of a specific size -- and although I do respect
someone's "No Metals" labels, I'm darned sure many other people DON'T.
If you're really concerned about contamination of your glassware, store
it away from wbgeneral (ask Staff if you need extra space.)

Whew!  Better now.

Yes, me again --

As several people have pointed out, tomorrow is the 31st (darn, I was so
hoping it was already Thursday!) and there's actually another day's
reprieve.  As also pointed out, I neglected to mention that
requalification also applies to wbgeneral.

To reiterate, there are a total of five tests for all these wet benches:

- wbgeneral, wbdiff, wbsilicide, and wbnonmetal each have a station
specific test.
- in addition, there is a single test for wbdiff, wbsilicide, and
wbnonmetal which covers those procedures and equipment which are the
same for these stations.

All tests are available in Uli & Henry's office and should be returned
there when completed.

Please [continue to!] direct questions, comments [and complaints] to me.

Thanks,

Mary

Subject: Wet Bench Requalification...
Message-ID: <3B1669CA.C6A6EF3B@snf.stanford.edu>

Hello all --

I've been inundated with emails regarding the wet bench tests!  And yes,
indeed, the new policy is that the "Multi-Wet Bench" test DOES cover
wbsilicide, wbnonmetal, and wbdiff.  Only wbgeneral has its own test.

(My apologies for the misinformation in the last email -- I was on
vacation when the policy change was made and was thus clueless.  There
are still individual tests for each wet bench -- and I invite you all to
at least take a look at them [I see there's going to be a rush to Uli's
now - yeah, right].  Future users WILL have to take these individual
tests in addition to the Multi-Wet Bench test -- so lucky you!)

By the way, Uli says that very few people are filling out the section
correctly on what to write on the "blue cards" for the wbgeneral test.
This is probably because the operating procedures are not explicit (but,
rather, implicit) on this subject.  The purpose of the blue cards is to
let everyone know what chemicals are being used.  The policy is to use
chemical names, rather than jargon (like "BOE" or "Piranha") because
everyone should know what nasties they've just poured into a beaker, and
because some jargon just doesn't cut it ("Resist Stripper" -- yes,
haven't we all seen this?)  No, people are not going to be failed on the
test because of this -- BUT, make sure your blue cards are correct at
wbgeneral (you are forewarned!)
