Abstract:
A workpiece cleaning system comprising:a workpiece holding mechanism including a plurality of workpiece edge engaging members; a rotator mechanism coupled to said gripping members to rotate a planar workpiece engaged by said edge engaging members around an axis of rotation that is substantially perpendicular to a first surface of said workpiece and to an opposing second surface of said workpiece; a vapor phase outlet positioned to apply a vapor phase at a first temperature to said first surface of said planar workpiece while said workpiece is being rotated; and a liquid phase outlet positioned to apply a liquid phase at a second temperature less than said first temperature to said second surface of said planar workpiece while said workpiece is being rotated, said liquid phase cooling said workpiece such that there is substantial condensation of said vapor phase when it contacts said first surface.
