Polishing articles for electrochemical mechanical polishing of substrates

摘要

An article of manufacture, method, and apparatus are provided for planarizing a substrate surface. In one aspect, an article of manufacture is provided for polishing a substrate including a polishing article (205) having a body comprising at least a portion (310) of fibers coated with a conductive material, conductive fillers, or combinations thereof, and adapted to polish the substrate. In another aspect, a polishing article includes a body having a surface adapted to polish the substrate and at least one conductive element embedded in the polishing surface, the conductive element comprising dielectric or conductive fibers coated with a conductive material, conductive fillers, or combinations thereof. The conductive element may have a contact surface that extends beyond a plane defined by the polishing surface. A plurality of perforations (546) and a plurality of grooves (542) may be formed in the articles to facilitate flow of material through and around the polishing article.
