If you are asking for who has a critical point dryer in the Bay Area,
I'm pretty certain that our friends at UC Berkeley have a Tousimis unit
that is very similar to ours.
Let me know if you need contact information over there.
Thanks,
John

I have very little experience in critical point drying but here is
what I have learned this fall doing CPD.
(1) Do a trial run with your system first to know you can control the
temp of the water jacket accurately. This is important for maintaining
both temp and pressure, which can effect end results.
(2) Always try to let your gels sit overnight, and if possible in an
oven near 40-60 degrees C, to thoroughly form any bonds that are
available and complete the gelation.
(3) Depending on the gel your trying to dry, it may require several
hours of ethanol soaking to replace the water. I have learned that
many times it is necessary to move up in EtOH concentration in step
changes, starting near 10-20% and moving up to 200 proof. this could
take 2 or 3 days.
This may apply more to my system than your own and only some of my
gels have been successful, they have alot of glycerol in them, but
this is what I have learned thus far. I hope it helps.

I was wondering if anyone had experience in depositing chromium by magnetron sputtering and could offer some advice on how to produce smooth homogenous films.
I'll provide some TEM images and deposition conditions if anyone could offer help on how to improve the films.

All tools will be shutdown by Wed. afternoon. Most analytical tools
will be removed from the lab as well. At 5 pm the lab will officially
close for business. Thanks all, for cleaning up!
And see you next year -- the lab will still look like the same old car,
but will have a shiny new engine underneath --
Happy Holidays --

Process cooling water is back on. Maintenance crew is working in the
lab to bring tools up. Here's a summary:
- Work is being done on the network. Sunray Coral is fine (internal
network.) Access to remote Coral and SNF emails may be spotty.
- ASML, innotec, metalica, gryphon so far look on track to be up soon.
ETA is around 1 pm. (Thanks Gary & Jim).
- Amtetcher is down hard; heat exchanger pump didn't survive.
P5000etch, mrc, and lampoly are up or nearly so. Stsetch2 is getting
there (Thanks Cesar!)
Many thanks also to Tony Padilla, the Facilities tech who came in both
last night and this morning to check on the water.

The campus cooling water system is still being repaired. We've been
told it may be a few more hours. The campus cooling loop tempers the
building and lab air, so you will have noticed the lab getting quite
warm. Our building loop is cooled by the campus loop; we are now
running equipment using city water in the building loop. The
temperature is better now, but the pressure is much lower than most
tools would like, so some new equipment errors may arise.
The high water temperature appears to have caused our building loop to
spring a few significant leaks in the basement. So, there are concerns
that pressurizing our building loop may result in a flood. We are
scheduling additional Facilities and SNF staff in on Sunday morning to
be on-hand when the building loop is turned back on.
In short, tools with process cooling water problems will remain down for
the evening. We hope to be in a good position to restart tools in the
morning. Our apologies for the inconvenience, especially coming so
close to the shutdown. Please have patience as we all work through this.

We've just been informed that there's a cooling water problem throughout
the campus. There is flow, but the temperature is high. It is also
possible that there are irregularities in flow. Tools using cooling
water will not function if temperature and flow are not within certain
limits and will stop processing. Facilities believes the problem will
be resolved within a couple of hours. In the meantime, we have several
reports of tools with turbo and RF failure. The ASML will not reboot.
These are all likely due to the cooling water problem. Once the water
is brought back into spec, most tools will reset themselves. In the
meantime, please do not override or clear errors, or reboot tools that
make use of cooling water -- the tools are protecting themselves.
Thanks,
Your SNF staff
All the canisters are full and we should be just fine for manual
development as well.

We would like to try spin-on glass in our project and would like to know
if anyone would be kind enough to share a little spin-on glass with us.
We just need a little to spin one or two small chips. This SOG should
be SILICATE BASED only.
Thank you for your attention.

We've been asked: what time do lab bins need to be emptied? Please
clear items by noon Monday (Dec. 12). We know you're working hard to
get as much done as possible before the extended shutdown. Staff,
however, are stretching to get everything buttoned up before shutdown.
Please help by collecting and storing your belongings in a safe place.
Thanks,
Your SNF Staff

Subject: Bake Sale update
Dear All,
I want to say a huge thank you for everyone who bought goodies at the
bake sale or made a donation. We made a staggering $365...Wohoooo!
All the proceeds will be going directly to Insight World Aid.
I have cc'ed Nancy Smee who is one of the Board of Directors volunteering
for Insight, if you have any questions or interested to get involved.
In addition, I want to thank the amazing chefs who worked hard to make
this sale possible. A huge thank you to Maureen B, Hulda, Margaret,
Njoki, Mahnaz, Astrid, Uli, and Nancy for helping and working behind
the scenes.
Thank you all once again for your support and making this possible :)
Wish you all a Happy Holidays and a great start to the New year.

Try to make it through to night, Gary and Mario just added the last
bottles of developers to
canisters. we ordered 4 cases of developer, that is equivalent to 16
more gallons.
We have been told that we will get it by tomorrow morning ( thanks to
David, begging).
We have used 34 gallons of developer since last week.
Slow down people.

The critical permits have been approved so construction is officially
underway. The permit approvals were one of the key risk factors in this
project, so things are moving well and are on schedule.
Just a few reminders:
1. Make sure to remove all your personal items from the lab. ALL of
them. Remove them from bins, from WIP racks, from shared storage. If
someone you know isn't aware of this, please make sure they are informed
-- we will be losing about 1/3 of the bins in the lab to make way for
new equipment and stockroom supplies, so we will be revamping the lab
bin process. To start fresh, everyone will need to clear out all the
bins -- and rollarounds, and shelves, etc. Any personal items left in
the lab will be removed by Staff. We will store the items but please
understand we can't be responsible for possible loss or damage.
2. The last day the lab is open is Wednesday, 12/14/11. Because we
have to make the lab safe for construction, many tools will be brought
down before this date, as toxic gas lines need to be purged, wet bench
drains need to be flushed, all small tools will be removed from the
lab. A schedule for individual tool shutdowns has been posted to the
SNF website -- but be aware that dates may change as we get nearer to
the time. Please refer to the schedule, but check on Coral for details.
Finally, thank you for your patience -- we realize this renovation is
inconvenient for you all -- meaning your help and cooperation are that
much more appreciated --
Thanks again -

The SNF Staff in conjunction with Imina Technologies is pleased to present: NANOMANIPULATION WORKSHOP Monday December 5, 2011 The miBots™ are coming! Do you have a need for manipulation or sensing small samples in a microscope? If so, we invite you to see these novel nanopositioners for yourself at the Stanford NanoFabrication Facility in a FREE, hands-on workshop on December 5th in the Paul Allen Building, Auditorium Room 101X. Designed especially for light microscopy, SEMs and FIBs, these affordable, easy-to-use mini robots are virtually untethered and free to move independently, opening new vistas for manipulation and testing at the macro, micro, or nanoscale. Working individually or in groups, the miBot™ uses a variety of tools such as grippers, probes, and optical fibers so that, in addition to manipulating the sample, they can illuminate a nano workspace and conduct force or electrical measurements. Robust, mechanically and thermally stable, and vacuum-ready, these tiny trojans are a great, customizable solution for maneuvering and testing cells, nanostructures, semiconductor devices, LEDs, and MEMs. miBots will be working in the Paul Allen Building, Auditorium Room 101X from 10 AM till Noon. For more information, or to register for workshop, click here http://imina.ch/events/registration-form-workshops-california-december-2011. Imina will contact you in the week before the workshop to confirm and provide a map and directions. Want to learn more? Visit us at www.imina.ch or give Tom Levesque a call at (972) 318-0196. Regards, SNF Staff
SNF has purchased a new vacuum sealer in hope of eliminating some of
the pain of bagging all the wafer boxes and masks.
The new tool is on the table close to EPI for now, this will be
temporary.
I wrote a quick instruction and is taped to the table, add to it if I
have missed anything.
The bags are in a blue tray and bigger so two box of wafers can be
sealed easily. please note that bags are special order and should not
be used for other things.

Party will start at 1:30 due to delay on refreshment delivery.
