Subject: Update on process gases (BCl3, NF3)
Message-ID: <4E8504E6.9030000@stanford.edu>

Etcher users:

As you should note from the problem logs on equipment, we are running 
extremely low on BCl3 (pquest, p5000etch) and are out of NF3 (p5000etch, 
amtetcher).  If you have critical processes, you may wish to delay 
processing with BCl3.  If you are using BCl3, please make sure to watch 
your gas flows; abort the process if flows drop.

BCl3 has been on order for a month and is overdue, but Elmer has just 
been informed that it will ship tomorrow, due to arrive next Wednesday, 
Oct. 5.   Please be warned that your reservation on or near the arrival 
date may be taken over to allow for cylinder replacement and testing.

We do not have a status update for NF3 as yet.  The spare bottle was 
ordered in good time, but found to be empty.  A second bottle is overdue 
and we are trying to track it.

We deeply apologize for the disruptions.

Team Etch
(Elmer, Nancy, Cesar, Mike)
