Abstract: Implementations described herein generally relate to methods and apparatus for polishing substrates, more particularly, to methods and apparatus for identifying and/or tracking polishing material in a roll-to-roll polishing system. In one implementation, a method of polishing a substrate is provided. The method comprises advancing a polishing material across a surface of a platen. The polishing material has a polishing surface and an opposing backside surface and the backside surface has a pattern of identifying features formed thereon. The method further comprises sensing the movement of the pattern of identifying features past a detector assembly. The method further comprises controlling a position of the polishing material relative to the platen based on data received from the sensed movement of the pattern of identifying features.

Abstract: Embodiments of the present disclosure generally relate to methods of manufacturing polishing platens for use on a chemical mechanical polishing (CMP) system and polishing platens formed therefrom. A method of manufacturing a polishing includes positioning a polishing platen on a support of a manufacturing system. The manufacturing system includes the support and a cutting tool facing there towards. Here, the polishing platen includes a cylindrical metal body having a polymer layer disposed on a surface thereof and the polymer layer has a thickness of about 100 μm or more. The method further includes removing at least a portion of the polymer layer using the cutting tool to form a polishing pad-mounting surface. Beneficially, the method may be used to form a pad-mounting surface having a desired flatness or shape, such as a concave or convex shape.

Abstract: A method and apparatus for polishing a substrate that includes a polishing article comprising a polymeric sheet having a raised surface texture, which is formed on the surface of the polymeric sheet is provided. According to one or more implementations of the present disclosure, an advanced polishing article has been developed, which does not require abrasive pad conditioning. In some implementations of the present disclosure, the advanced polishing article comprises a polymeric sheet having a polishing surface with a raised surface texture or “micro-features” and/or a plurality of grooves or “macro-features” formed in the polishing surface. In some implementations, the raised surface texture is embossed, etched, machined or otherwise formed in the polishing surface prior to installing and using the advanced polishing article in a polishing system. In one implementation, the raised features have a height within one order of magnitude of the features removed from the substrate during polishing.
