From nnelsonf at uwaterloo.ca Tue Aug 6 16:39:10 2019 From: nnelsonf at uwaterloo.ca (Nathan Nelson - Fitzpatrick) Date: Tue, 6 Aug 2019 20:39:10 +0000 Subject: [Qnfcf-intlvac-ebeam] New Gold crucible Message-ID: <473CE7E9-8648-47F3-A76E-C641B70B38B1@uwaterloo.ca> Hi Intlvac users, Gold has been migrated back to a FABMATE type vitreous carbon crucible on the Intlvac. We tried two different styles of Molybdenum crucibles in an effort to deliver higher quality films, but Gold ?wicking? out of this crucible type caused inconsistent thermal contact with the pocket. This variation in thermal contact caused many large ?overshoots? during deposition and therefore wasted gold. We will still aim to make a Molybdenum crucible process available on request, but this will no longer be the standard process on the Intlvac. Please contact me if you have any questions.
