    摘要: Embodiments of the present invention provide methods of electroprocessing a substrate. One embodiment of the present invention provides a method comprises pressing a substrate against a polishing pad with a force less than about two pounds per square inch, the substrate contacting a first electrode of the polishing pad, applying an electrical bias to the substrate with the first electrode relative to a second electrode of the polishing pad, wherein the second electrode is disposed below the second electrode, and biasing a third electrode disposed in the polishing pad radially outward of the second electrode.

    摘要: A carrier head and a method of cleaning the carrier head are disclosed. The carrier head may have one or more openings through a sidewall that extend into a cavity within the carrier head using a fluid passage. The openings may each have a lip. The lip may have a chamfered edge. Additionally, a fluid passage may slope generally downward from the openings to the cavity. The chamfered lips and the sloped fluid passage reduce back splashing and help ensure that sufficient rinsing fluid reaches the cavity to rinse polishing fluid and particles from the carrier head. The present invention relates to carrier heads for polishing or planarizing semiconductor substrates by chemical mechanical polishing (CMP) or electrochemical mechanical polishing (ECMP). The cavities in the carrier head are cleaned by rinsing fluid (i.e., liquid or gas) from inside the cavity towards a substrate receiving side of the carrier head.

    摘要: A retaining ring for use with electrochemical mechanical processing is described. The retaining ring has a generally annular body formed with a conductive portion and a non-conductive portion. The non-conductive portion contacts the substrate during polishing. The conductive portion is electrically biased during polishing to reduce the edge effect that tends to occur with conventional electrochemical mechanical processing systems.
