Abstract
A method and apparatus for coating and baking and deposition of surfaces on glass substrate or flexible substrate, such as films and thin glass sheets or other similar work pieces as it transitions thru and between small gaps of aero-static or hydro-static porous media bearings and differentially pumped vacuum grooves, in a non-contact manner, in order to process within a vacuum environment. The process is also intended to incorporate simultaneous and immediately sequential ordering of various processes.
