Zusammenfassung:	Methods for processing photomasks are provided herein. In some embodiments, a method for processing a photomask may include providing a photomask to a substrate support within a process chamber; providing a process gas to the process chamber having the photomask disposed therein; providing a negative or zero voltage to a substrate support cathode having the photomask disposed thereon; providing a source RF power to an anode coupled to the process chamber to ignite the process gas to form a plasma; and processing the photomask.
