  • Patent number: 10076817
    Abstract: A chemical mechanical polishing apparatus includes a plate on which a substrate is received, and a movable polishing pad support and coupled polishing pad which move across the substrate and orbit a local region of the substrate during polishing operation. The load of the pad against the substrate, the revolution rate of the pad, and the size, shape, and composition of the pad, may be varied to control the rate of material removed by the pad.

  • Publication number: 20180207770
    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.

  • Patent number: 9662762
    Abstract: A polishing system include a support to hold a substrate having a substrate surface to be polished, a carrier to hold a polishing pad in contact with the substrate surface, and a pressure applicator to apply pressure at a selected region of a back surface of the polishing pad. The back surface is opposite to the polishing surface. The pressure applicator includes an actuator and a body configured to be moved by the actuator into and out of contact with the selected region of the back surface of the polishing pad.

  • Publication number: 20160176014
    Abstract: Embodiments of the present invention provide systems, apparatus, and methods for an improved polishing head including an upper portion and a lower portion, the lower portion adapted to hold a substrate and to tilt relative to the upper portion, the tilt enabled by a spherical bearing, wherein the lower portion is adapted to tilt while rotating the substrate against a rotating polishing pad so that the lower portion remains flush against the rotating polishing pad while resisting lateral friction force generated by the rotating polishing pad contacting the substrate and pushing the substrate laterally against the lower portion. Numerous additional aspects are disclosed.
