Abstract
Methods for treating texturized surfaces of sputter targets in order to improve adhesion and retention of deposited particles thereon. The target surfaces may first be texturized by a precursor texturizing method such as bead blasting, grit blasting, plasma spraying, or a twin-wire-arc spraying (TWAS) method. The thus textured surface is then sprayed or blasted with ice particles to form an optimized textured surface. The ice particles may comprise sublimable particles such as frozen carbon dioxide or dry ice. Also, argon may be used as exemplary ice particles.
