Monday, 6/7 Chilled Water shutdown ....

SNF Lab Members:

As a number of you know, the pressure of the process chilled water to
the building has been 20-30 PSI higher than normal because of the
failure of a component known as the expansion tank.

The chilled water system will be shutdown for a period of several hours
starting at 7 a.m. next Monday, June 7 in order to replace this
component. While this is being done, valves will be added to the system
so that future changes could take place without shutting the entire system.

We apologize for this inconvenience but hope that first thing Monday
morning will be a minimal disruption to all of you. This shutdown
should not affect wet benches, characterization tools, or most
lithography equipment (except for the ASML). Most etchers, deposition
tools, furnaces, and LPCVD tools WILL be unavailable during this time
window.

Please let us know if you have any questions or concerns.

Thanks,

John
