Summary performance data:

Chamber base pressure <3e-7 Torr
Load lock base pressureb <1e-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 sequenc
