Abstract

Disclosed is a shielding assembly for use within a substrate deposition processing chamber. The shielding assembly permits sputtering and evaporation processes to take place without the target material depositing upon the internal non-disposable surfaces of the chamber. The shielding assembly is of an improved construction which permits it to be uncoupled from an adapter plate without the need for removing the adapter plate from the deposition chamber.
