SNF Lab Members:

As of about 7 a.m. this morning, steam has been restored to the lab.  As 
a result, we now have the ability to control temperature and humidity in 
the cleanroom and temperature and humidity are close to their normal range.

However, because the lab and tools in it were quite cold overnight 
(16C/61F), anything with significant thermal mass will not be back to 
operating temperatures for some time.  In particular, I expect that this 
will include the ASML and ebeam tools.  Additionally, any room 
temperature baths such as 50:1 HF and BOE baths will likely take a 
couple of hours to get back to their normal daytime temperatures.

Please check each tool carefully before use and be extra vigilant in 
looking for anamolous behavior.

We apologize for this extended outage but are doing our best to recover 
as quickly as possible.
