From nlatta at stanford.edu Fri Aug 15 11:54:23 2008 From: nlatta at stanford.edu (Nancy Latta) Date: Fri, 15 Aug 2008 11:54:23 -0700 Subject: New Stand-By Procedure Message-ID: <48A5D0DF.6070000@stanford.edu> Dear STS Etchers, The recent problems with the chamber isolation valve leak has given us to opportunity to review our standard operating procedure with regard to the stand-by or idle mode. In the past we have left the loadlock vented. From now on users of the tool should leave the loadlock under vacuum after completing their runs. This will help in decreasing wear and tear on the turbo pump. It also is consistent with the procedures at stsetch2. In order to leave the loadlock under vacuum after your work is completed you will need to load a 'fake' or 'phantom' wafer. You simply click on the LOAD button. The software will falsely indicate a wafer is on the chuck. When you approach the etcher to begin etching you will need to UNLOAD this fake wafer and VENT the loadlock. This message will be posted in the coral comments for stsetch and new operating instructions will be placed into the logbook. Unfortunately, the website will continue to show the old operating instructions. I have attached a copy of the new instructions to this message. Please let us know if you have any comments or questions. And thanks for your attention. Team Etch -------------- next part -------------- A non-text attachment was scrubbed...
