    Abstract: An improved polishing pad and process for polishing a multitude of materials is invented. The process includes steps to liberate material from the surface of the pad and in doing so form a desired surface texture for polishing, while allowing the bulk of the pad to remain solid and hence less compressible and stiffer. These material properties yield a polishing better suited for applications such as semiconductor wafer silicon dioxide, damascene tungsten metal, damascene copper polishing, and the like.

    Abstract: Disclosed is a method of applying particles to a coated backing. A first layer of particles is created over a second layer of particles on a support surface and the first layer of particles is different in at least one property from the second layer of particles. A coated backing is positioned above the first and second layer of particles. An electrostatic field is applied simultaneously to the first and second layer of particles such that the first layer of particles closer to the coated backing are preferentially attracted to the coated backing first before the second layer of particles.

    Abstract: This invention encompasses abrasive articles that have a coating, typically made of at least a binder and abrasive particles, selectively removed from a portion of an exposed abrading surface of the article in order to inscribe a detectable marking on the abrasive article. Suitable coated abrasive articles include both articles that have the binder and abrasive particles sequentially coated on a backing as a make coat and deposited abrasive particles as well as articles that have the binder and abrasive particles simultaneously coated on the backing as a slurry coat. Coated abrasive articles that are particularly preferred include articles that have an exposed abrading or abrasive surface that is a textured, three-dimensional surface.
