Claim 6:
7. The workpiece processing system of claim 6, wherein the cooling chamber comprises a vacuum port and a purge gas port in fluid communication with the chamber volume, the workpiece processing system further comprising:
a vacuum valve configured to provide selective fluid communication between the vacuum source and the vacuum port; and
a purge gas valve configured to provide selective fluid communication between the purge gas source and the purge gas port, wherein the vacuum valve and purge gas valve are configured to selectively flow the purge gas from the purge gas port to the vacuum port, and wherein the controller is further configured to control the vacuum valve and the purge gas valve to selectively flow the purge gas from the purge gas port to the vacuum port at the predetermined pressure concurrent with cooling of the workpiece, thereby generally evacuating the respective outgas material from the chamber volume and preventing a release of the respective outgas material to the first environment.
