    摘要: A carrier head for chemical mechanical polishing of a substrate includes a base and a flexible membrane extending beneath the base. The flexible membrane includes a central portion with an outer surface providing a substrate receiving surface, a perimeter portion connecting the central portion to the base, and at least one flap extending from an inner surface of the central portion. The flap divides a volume between the flexible membrane and the base into a plurality of chambers, and the flap includes a laterally extending first section and an angled second section extending beneath the first section and connecting the laterally extending first section to the central portion.

    摘要: The present invention relates to an apparatus and method for improving and speeding up substrate loading process. One embodiment provides a method for vacuum chucking a substrate. The method comprises venting a center chamber of a flexible membrane configured for mounting the substrate, moving the substrate such that a backside of the substrate is in full contact with the flexible membrane, and vacuuming the center chamber to vacuum chuck the backside of the substrate to the flexible membrane.
