Beschreibung
Zusammenfassung:	Methods of polishing a patterned surface of an electrostatic chucking (ESC) substrate support to be used in plasma assisted or plasma enhanced semiconductor manufacturing chambers are provided herein. In particular, embodiments described herein, provide polishing methods that round and debur the edges of elevated features and remove dielectric material from the non-substrate contacting surfaces of a patterned substrate support to reduce defectivity associated therewith.
