Abstract:
1. An apparatus for cooling a planar substrate positioned in a vacuum enclosure, the apparatus comprising: support means for supporting the substrate within the vacuum enclosure, the substrate having a first surface and an opposite second surface, the second surface having one or more adherent films thereon; a first cooling plate positioned proximate the first surface of the substrate, a first spatial volume being formed between the first cooling plate and the first surface of the substrate; a second cooling plate positioned proximate the second surface of the substrate, a second spatial volume being formed between the second cooling plate and the second surface of the substrate; means for sealing the first and second spatial volumes from an ambient pressure environment within the vacuum enclosure; means for admitting a gas under controlled pressure conditions from an external source into the first and second spatial volumes such that the pressure of the gas in the first spatial volume is substantially equal to the pressure of the gas in the second spatial volume; and means for controllably cooling the first and second cooling plates.
