    摘要: Methods, articles of manufacture, and apparatus are provided for depositing and planarizing one or more layers of material on a substrate, or combinations thereof, are disclosed. In one embodiment, an article of manufacture is provided for polishing a substrate, comprising a polishing article having a polishing surface, a plurality of perforations formed in at least a portion of the polishing article for flow of material therethrough, and a plurality of grooves disposed in the polishing surface. The article of manufacture may be used in a method for processing a substrate, comprising positioning the substrate in an electrolyte solution containing a polishing article, optionally depositing a material on the substrate by an electrochemical deposition method, and polishing the substrate with the polishing article.

    摘要: A method and apparatus for the removal of a deposited conductive layer along an edge of a substrate using an electrode configured to electro polish a substrate edge are disclosed. The electro polishing of the substrate edge may occur simultaneously during electrochemical mechanical processing (Ecmp) of a substrate face. In one embodiment, a power source applies a bias between the substrate and at least two electrodes. The electrodes form a first electrode zone proximate the substrate edge at a sufficient potential to electro polish the substrate edge, thereby removing the conductive layer from the substrate edge. A second electrode zone with a lower potential than the first electrode zone is aligned proximate the substrate face during processing to enable Ecmp of the substrate face.
