    摘要: A retainer is used with an apparatus for polishing a substrate. The substrate has upper and lower surfaces and a lateral, substantially circular, perimeter. The apparatus has a polishing pad with an upper polishing surface for contacting and polishing the lower face of the substrate. The retainer has an inward facing retaining face for engaging and retaining the substrate against lateral movement during polishing of the substrate. The retaining face engages a substrate perimeter at more than substantially a single discrete circumferential location along the perimeter.

    摘要: A carrier head for a chemical mechanical polishing apparatus a flexible membrane that applies a load to a substrate in a loading area with a controllable size. One pressurizable chamber in the carrier head controls the size of the loading area, and another chamber controls the pressure applied to the substrate in the loading area.

    摘要: A carrier head for a chemical mechanical polishing apparatus includes a flexible membrane that applies a load to a substrate. A volume between the flexible membrane and a carrier structure provides a chamber. A body located in the chamber has a first portion that applies pressure to a first region of an upper surface of a central portion of the flexible membrane and a second portion that is separable and movable into contact with a second region of the upper surface of the central portion of the flexible membrane.
