Summary performance data:

Chamber base pressurea < 3e-7 Torr
Load lock base pressureb < 2E-5 Torr

a. After 12 hours bake out at 80˚C
b. Load lock pumps down to 6E-5Torr in less than three minutes. It takes less than five minutes from  sample loading i.e. from the load lock to process platen with load lock pump down sequence.

Process specification

1. Pt etch with rotation and adjustable tilt.
