摘要： A carrier head for a chemical mechanical polishing apparatus is described. The carrier head has a base, a rigid body, a membrane and a pressurizing structure. The rigid body is movable relative to the base and includes a downwardly-extending projection. The membrane has a mounting surface for a substrate. The membrane extends below the base to provide a chamber between the base and the membrane. The pressurizing structure applies a downward pressure on the rigid body to cause a lower surface of the rigid body to press on an inner surface of the membrane.

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 platen for chemical mechanical polishing of a substrate includes a surface upon which a polishing pad can be placed, a support structure, and a controller. The surface has a first region and a second region and is operable to exert force against the polishing pad during polishing. The support structure is located beneath the second region and is operable to cause the second region to exert more force than the first region. The controller is operable to adjust the amount of force that is exerted by the second region.

摘要： A carrier head for a chemical mechanical polishing apparatus includes a flexible membrane, the lower surface of which provides a substrate-receiving surface. The carrier head may include a projection which contacts an upper surface of the flexible membrane to apply an increased load to a potentially underpolished region of a substrate. Fluid jets may be used for the same purpose.
