摘要： A polishing system includes a carriage arm having an actuator disposed on a lower surface thereof. The actuator includes a piston and a roller coupled to a distal end of the piston. The polishing system includes a polishing pad and a substrate carrier suspended from the carriage arm and configured to apply a pressure between a substrate and the polishing pad. The substrate carrier includes a housing, a retaining ring, and a membrane. The substrate carrier includes an upper load ring disposed in the housing. The roller of the actuator is configured to contact the upper load ring during relative rotation between the substrate carrier and the carriage arm. The actuator is configured to apply a load to a portion of the upper load ring thereby altering the pressure applied between the substrate and the polishing pad.

摘要： 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.

摘要： An apparatus for chemical mechanical polishing (CMP) of a substrate is described herein. The apparatus includes an extension disposed between a retaining ring and a chucking membrane. The extension is disposed radially outward from the edge of the substrate and is configured to contact the retaining ring during substrate processing. The extension provides a repeatable and controlled point of contact between the retaining ring and the chucking membrane. The extension may have multiple configurations, such that the contact point between the retaining ring and the chucking membrane is set at a pre-determined location or such that the contact point is moveable by an adjustable stop.
