Claim 8:
9. A method, comprising:
removing a substrate from a processing chamber;
placing by a substrate transfer robot a substrate support cover on a substrate support disposed in the processing chamber, the substrate support cover comprises a bulk material layer, and a coating of a fluoride material, wherein the coating is exposed to a processing region in the processing chamber, wherein the bulk layer further comprises a first surface in contact with the surface of the substrate support, a second surface opposite the first surface, a third surface extending from the first surface and facing the side surface of the substrate support, a fourth surface extending from the second surface and opposite the third surface, and a fifth surface connecting the third surface and the fourth surface,
performing a cleaning process in the processing chamber while the substrate support cover is on the substrate support, the fluoride material of the substrate support cover being exposed to a cleaning gas or cleaning species during the cleaning process.
