Abstract:
1. An apparatus for conditioning a substrate with a conditioning gas comprising a reactive gas component, the apparatus comprising: a chamber, isolatable from the ambient environment, into which a substrate having generally planar top and bottom surfaces may be placed at a predetermined substrate orientation, and into which said conditioning gas may be fed to condition the substrate, the chamber being provided with a first window transparent to at least one of UV and IR light, the first window positioned so that light may be transmitted through the first window and onto the top surface of the substrate when the substrate is positioned in the chamber at said predetermined substrate orientation, the chamber being provided with a second window transparent to at least one of UV and IR light, the second window positioned so that light may be transmitted through the second window and onto the bottom surface of the substrate when the substrate is positioned in the chamber at said predetermined substrate orientation, a vacuum source operably communicating with the chamber whereby the chamber may be evacuated to a pressure below ambient pressure during conditioning of said substrate within the chamber, and a source of said conditioning gas operable to feed said conditioning gas to the chamber.
