Abstract:
1. A process for rapidly cooling a substrate in a vacuum environment, comprising: positioning a planar substrate having upper and lower surfaces in the vacuum environment, the lower surface of the substrate having one or more adherent films thereon; positioning an upper cooling plate above said substrate such that a lower surface of said upper cooling plate is in close proximity to said upper surface of said substrate, thereby forming an upper spatial volume between said lower surface of said upper cooling plate and said upper surface of said substrate; positioning a lower cooling plate below said substrate such that an upper surface of said lower cooling plate is in close proximity to said lower surface of said substrate, thereby forming a lower spatial volume between said upper surface of said lower cooling plate and said lower surface of said substrate; sealing said upper and lower spatial volumes from the vacuum environment, wherein the upper and lower spatial volumes are separately sealed from the vacuum environment; admitting a gas under controlled pressure into said upper spatial volume; admitting a gas under controlled pressure into said lower spatial volume, the pressure of the gas in the upper spatial volume being substantially equal to the pressure of the gas in the lower spatial volume; and controllably cooling said upper and lower cooling plates.
