Beschreibung
Zusammenfassung:	A PVD apparatus can be operated in a cleaning mode to remove material from an electrically conductive feature formed on a semiconductor substrate. The semiconductor substrate with the electrically conductive feature formed thereon is positioned on a substrate support in a chamber of the PVD apparatus. A shutter is deployed within the chamber to divide the chamber into a first compartment in which the semiconductor substrate and the substrate support are positioned, and a second compartment in which a target of the PVD apparatus is positioned. A first plasma is generated in the first compartment to remove material from the electrically conductive feature and a second plasma is simultaneously generated in the second compartment to clean the target.
