Abstract:
1. A method of processing an electronic device comprising: loading a workpiece into a processing chamber, the processing chamber at a loading temperature; operating the processing chamber at a first temperature while the workpiece is being processed; decreasing the temperature within the processing chamber from a first temperature to a second temperature less than the first temperature and less than the loading temperature; removing the workpiece and a carrier holding the workpiece from the processing chamber while decreasing the temperature within the processing chamber, by turning off power to all heating elements used to control the temperature within the processing chamber, from the second temperature to a third temperature lower than the first temperature and the second temperature; increasing the temperature within the processing chamber to a fourth temperature greater than the second temperature and less than the first temperature while the processing chamber has no workpiece or carrier within; and maintaining the temperature within the processing chamber at the fourth temperature for a time period to perform an outgassing operation closing a shutter adjacent to and outside of the processing chamber after the workpiece and the carrier are removed, wherein closing the shutter is performed after removing the workpiece and before increasing the temperature, the shutter not sealing the processing chamber from the ambient environment.
