    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 polishing semiconductor substrates. In one embodiment, two polishing heads are mounted on two independent pivoting arms that share one pivot point. Each of the pivoting arms enable the corresponding polishing head direct access to two polishing stations. The polishing system of the present invention provides flexibility and improves throughput.

    摘要: A polishing pad for use in a chemical mechanical polishing system is provided. The pad is mounted to a rotatable platen and comprises a polishing surface and a deflection surface which provides a desired degree of rigidity and compliance to the pad when brought into contact with a substrate. The deflection surface may comprise one or more passageways extending through the pad which vent to atmosphere. In one embodiment, the deflection area defines a raised area and a recessed area. The raised area provides a mounting surface for the platen while the recessed area allows for compliance of the pad. In another embodiment, the deflection area comprises a plurality of channels defining a plurality of slanted protrusions. The channels may be non-intersecting such that the slanted protrusions are elongated portions disposed on the pad. Alternatively, the channels may be intersecting such that the slanted protrusions are isolated from one another and are disposed on the pad in spaced relation.
