    摘要: The polishing pad for a chemical mechanical polishing apparatus, and a method of making the same. The polishing pad has a covering layer with a polishing surface and a backing layer which is adjacent to the platen. A first opening in the covering layer with a first cross-sectional area and a second opening in the backing layer with a second, different cross-sectional area form an aperture through the polishing pad. A substantially transparent polyurethane plug is positioned in the aperture, and an adhesive material fixes the plug in the aperture.

    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.
