If you planned to come to SNF today, you won't be able to do much. While you can log into the sunrays, the coral screen never comes up and you cannot enable any equipment. I left a message for John Shott already and hopefully he or whoever can and does fix the system will email this list when it is back up. Two other folks have verifed the same problem on their accounts.

Notices to this effect have been placed by the machines. Any files or folders that are below "C:/save" on either system will be backed up and restored after the systems are reloaded. Anything else on these systems will be lost. Please notify me if there is a problem with this. The object is to cleanup the systems and to load the most current version of L-Edit on the systems.

Starting last Friday afternoon the system start giving "Wafer vacuum loss" I did do training on Monday and got that error and still was able to get by and after me two more people were able to use it. Some one turned the system OFF to clear the error and we could not turn the system back on. Mario has spent long hours on it and fixed few of the problems caused by turning off the system. There is a sign posted on the system that it says Do not turn the system off. I am not sure how to state that I do not want you to turn the system off. There is a procedure we follow when we turn it off, when you turn it off and on again the stage bangs it self to the sides and causes more problems. Now, one problem and a wrong action lead to a much bigger problem. karl suss has been called and we are waiting to see when they are able to send some one down to fix the problem. I will send an email to notify you as soon as the system is up. mahnaz -------------- next part -------------- An HTML attachment was scrubbed...

The workshop is devoted to cross-pollination of techniques available in the fields of chemical and physical nanotechnology through discussions of new developments, exploring ways of applying chemical techniques to nanofabrication as well as applying nanofabrication techniques to chemistry. At the end of the day, a panel discussion will summarize the current major issues in the fields. Seating is limited so please register early. The registration fee is $75 ($50 for students) if received prior to November 1 and $100 thereafter ($75 for students).

This seminar presents an overview of the analog front end (AFE) design for a digital subscriber loop (DSL) modem. Such an AFE is composed of various analog circuit blocks including analog to digital convertor (ADC), digital to analog convertor (DAC), filter, low noise amplifier (LNA), voltage controlled crystal oscillator (VCXO), phase locked loop (PLL), etc., all integrated on a single chip.

It is extremely important to always read the labels on all chemical bottles before adding chemicals to a hot pot or etch tank. What we think happened last week is that a user added 49% HF instead of H2O2 to H2SO4 in one of the Piranha resist strip hot pots. The problem is that such a mixture strips oxide along with the resist. Since this happened at least once before this past year and since 49% HF is probably the worst acid that we use in the lab, we need to do something more than just sending notes. Starting today, we are attaching a BRIGHT RED TIE WRAP to the top of all bottles of 49% HF before they come into the lab. Hopefully, this will stop users from confusing HF and H2O2 bottles. Depending on how this works out, we are consider attaching other color tie wraps to other acid bottles in the pass-through carts. Thanks, Jim McVittie
