Please note that the cleanroom humidity will be out of
specified limits on Friday during the ultrapure water outage. This can impact
various operations, but can have a very pronounced affect on photo-speed in
lithography operations utilizing POSITIVE PHOTORESIST.
Thank you again for your patience and cooperation,
