System has been in Active idle (~700c) for two days.
-
I ran 5 Si deposition after Narii's Ge test. Each wafer looked better the the previous. The last wafer and a couple of light haze spots.
-
I am leaving the system in Active Idle overnight and yellow lighing the tool.

The susceptor has been changed... if you are running Ge or low temperature Si you should run a test before committing "good" wafers. Your process conditions may have changed.
