摘要 |
An Exhaust Gas Analyzer (EGA) subsystem for monitoring exhaust gasses, for controlling and rapidly adjusting the processing conditions within a processing chamber in a thermal processing unit used for heating-treating wafers before and/or during Post Application Bake (PAB) procedures. The EGA subsystem can be used to control and/or optimize the heat-treating of coated wafers at different bake plate temperatures, and the EGA subsystem can provide a high wafer throughput.
