More Information
Summary:Contamination from outgassing during a deposition process is addressed by a series of equipment enhancements, including throttle valves, a dual air curtain, and a residual gas analysis (RGA) monitor. The dual air curtain can be configured to flow a first gas during wafer processing and a second gas during wafer unloading, to re-direct and capture outgassed species. The dual air curtain and the throttle valves can be programmed in an automated feedback control system that utilizes data from the RGA monitor.
