FLOW-FORMED CHAMBER COMPONENT HAVING A TEXTURED SURFACE

摘要

A method of fabricating a component for a substrate processing chamber involves providing a preform having internal and external surfaces, and providing a mandrel having a textured surface with a pattern of textured features comprising protrusions and depressions. The internal surface of the preform component is contacted with the textured surface of mandrel, and a pressure is applied to the external surface of the preform. The pressure is sufficiently high to plastically deform the preform over the textured surface of the mandrel to form a component having a textured internal surface comprising the pattern of textured feature that are shaped and sized to adhere process residues generated in the processing of substrates.
