PECVD PROCESS CHAMBER WITH COOLED BACKING PLATE

摘要

The invention generally relates to a plasma enhanced chemical vapor deposition chamber for depositing amorphous or microcrystalline silicon on a glass substrate to fabricate solar voltaic cells. The chamber includes a backing plate having at least one fluid receiving conduit to receive cooling fluid to remove heat generated within the chamber by the plasma, thereby stabilizing and cooling the backing plate to assure the uniformity of deposition of materials on the surface of the substrate.
