What does the Cycle Do?The Cycle mode will then:Pump the chamber to 0.05 mbar;Open argon flush then close;Pump to 0.15 mbar;Open argon flush then close;Open leak valvePump to 0.15 mbarSwitch on HV;Sputter at preselected current for preselected time/thickness
Remove samplesLift the Target assembly.CAREFUL the glass jar may stick to the top O-ring. HOLD THE GLASS while lifting the target assembly.Remove samples
ShutdownReplace glass jar;Close lid (target assembly)Close inline valve on argon lineTurn on Power and let chamber pump for a minute.Turn off PowerClose Valve on top of Argon Bottle.
Film Thickness Monitor (FTM)Coatings can also be deposited using the FTM.Density and Tooling factors currently in memory can be displayed by pressing the relevant button.
