    摘要: A polishing apparatus includes a turntable with an abrasive cloth mounted on an upper surface thereof, and a top ring disposed above the turntable for supporting a workpiece to be polished and pressing the workpiece against the abrasive cloth under a predetermined pressure. The turntable and the top ring are movable relatively to each other to polish a surface of the workpiece supported by the top ring with the abrasive cloth. The abrasive cloth has a projecting region on a surface thereof for more intensive contact with the workpiece than other surface regions of the abrasive cloth. The projecting region has a smaller dimension in a radial direction of the turntable than a diameter of the workpiece when the projecting region is held in contact with the workpiece. A position of the projection region is determined on the basis of an area in which the projecting region acts on the workpiece.

    摘要: A polishing apparatus makes it possible to accurately detect the temperature of a workpiece during polishing and to perform polishing end point determination on the basis of this detected temperature. The polishing apparatus polishes irregularities in a surface of a workpiece such as for example a semiconductor wafer to a flat and mirror-like finish. A top ring holding a semiconductor wafer is provided with a temperature sensor. Frictional heat generated in the semiconductor wafer by polishing is detected by the temperature sensor, and a polishing end point is determined on the basis of the detected temperature.
