    Abstract: A carrier head includes a base assembly, a substrate mounting surface connected to the base assembly, and a plurality of segments disposed circumferentially around the substrate mounting surface to provide a retaining ring to surround a substrate mounted on the substrate mounting surface. An inner surface of each of the plurality of segments is configured to engage the substrate, and each segment of the plurality of segments of the retaining ring is pivotally connected to the base assembly such that a lower portion of each segment of the retaining ring is swingable toward and away from the substrate.

    Abstract: A polishing system includes a platen having a top surface to support a main polishing pad. The platen is rotatable about an axis of rotation that passes through approximately the center of the platen. An annular flange projects radially outward from the platen to support an outer polishing pad. The annular flange has an inner edge secured to and rotatable with the platen and vertically fixed relative to the top surface of the platen. The annular flange is vertically deflectable such that an outer edge of the annular flange is vertically moveable relative to the inner edge. An actuator applies pressure to an underside of the annular flange in an angularly limited region, and a carrier head holds a substrate in contact with the polishing pad and is movable to selectively position a portion of the substrate over the outer polishing pad.

    Abstract: A chemical mechanical polishing apparatus includes a plate on which a substrate is received, and a movable polishing pad support and coupled polishing pad which move across the substrate and orbit a local region of the substrate during polishing operation. The load of the pad against the substrate, the revolution rate of the pad, and the size, shape, and composition of the pad, may be varied to control the rate of material removed by the pad.

    Abstract: A polishing system include a support to hold a substrate having a substrate surface to be polished, a carrier to hold a polishing pad in contact with the substrate surface, and a pressure applicator to apply pressure at a selected region of a back surface of the polishing pad. The back surface is opposite to the polishing surface. The pressure applicator includes an actuator and a body configured to be moved by the actuator into and out of contact with the selected region of the back surface of the polishing pad.

    Abstract: Embodiments herein generally relate to chemical mechanical polishing (CMP) systems used in the manufacturing of electronic devices. In one embodiment, a substrate carrier for polishing a surface of a substrate includes a retaining ring configured to surround a substrate during a polishing process. The retaining ring includes a first surface that is configured to contact a surface of a polishing pad during the polishing process, a second surface that is on a side of the retaining ring that is opposite to the first surface, and an array of recesses formed in the second surface. The substrate carrier for polishing a surface of a substrate also includes a plurality of load bearing pins where each load bearing pin of the plurality of load bearing pins includes a contact surface and a body that has a length, and at least a portion of the length of each load bearing pin of the plurality of load bearing pins is disposed within each recess of the array of recesses and the contact surface of each load bearing pin of the plurality of load bearing pins is positionable relative to a surface of the recess in which it is disposed during the polishing process.

    Abstract: A chemical mechanical polishing apparatus includes a platen to support a polishing pad, an actuator, a carrier head to hold a surface of a substrate against the polishing pad, a motor to generate relative motion between the platen and the carrier head so as to polish an overlying layer on the substrate. The platen has a central section with an upper surface and an annular flexure surrounding or surrounded by the central section and having a top surface with a first edge adjacent to and coplanar with the upper surface and a second edge farther from the central section. The actuator is arranged to bend the annular flexure along an entire circumference of the annular flexure so as to modify a vertical position of the second edge of the annular flexure relative to the central section.
