    摘要: A compressible film that is detachably securable to a surface of a rigid structure in the carrier head. The compressible film has a plurality of apertures positioned to create a non-uniform pressure distribution on a substrate during polishing so as to improve polishing uniformity. The apertures may be spaced and positioned to provide a pressure distribution on the substrate that is locally uniform but globally non-uniform.

    摘要: A substrate is maintained beneath a substrate mounting surface with a retaining ring that includes a generally annular lower portion having a bottom surface for contacting the polishing surface during polishing, and a generally annular upper portion having a bottom surface joined to the lower portion and a top surface fixed to and abutting the base. The lower portion is made of a plastic and the upper lower portion is made of a metal which is more rigid than the plastic.

    摘要: A carrier head for a chemical mechanical polishing apparatus. The carrier head includes a housing, a base, a loading mechanism, a gimbal mechanism, and a substrate backing assembly. The substrate backing assembly includes a support structure positioned below the base, a substantially horizontal, annular flexure connecting the support structure to the base, and a flexible membrane connected to the support structure. The flexible membrane has a mounting surface for a substrate, and extends beneath the base to define a chamber.

    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.
