    摘要: A method and apparatus for determining a planar end point on a workpiece such as a semiconductor wafer in a polishing process for polishing the workpiece to a flat mirror finish. The workpiece having an uneven surface is held by a top ring and pressed against a polishing platen. The workpiece is moved relative to the polishing platen to polish the workpiece, and a change in a frictional force between the workpiece and the polishing platen is detected. A reference time when the workpiece having an uneven surface is polished to a flat surface is determined based on the change of the frictional force between the workpiece and the polishing platen. The time when a certain period of polishing time from the reference time elapses is determined as an endpoint on the workpiece.
