    摘要: A polishing cloth mounted on a turntable is dressed by bringing a dresser in contact with the polishing cloth for restoring the polishing capability of the polishing cloth. The dressing is performed by measuring heights of a surface of the polishing cloth at radial positions of the polishing cloth in a radial direction thereof, determining a rotational speed of the dresser with respect to a rotational speed of the turntable on the basis of the measured heights, and dressing the polishing cloth by pressing the dresser against the polishing cloth while the turntable and the dresser are rotating. The dresser has an annular diamond grain layer or an annular SiC layer.

    摘要: A predetermined amount of liquid such as water is supplied to a backside surface of a workpiece such as a semiconductor wafer. Such liquid is a workpiece retaining liquid and is attached to a concave workpiece holding surface of a top ring. The workpiece is positioned between a turntable and the top ring and is polished by an abrasive cloth on the turntable while the workpiece is being pressed against the turntable by the top ring. While polishing, the workpiece is deformed toward the concave workpiece holding surface of the top ring, and a curvature of the deformed workpiece is controlled by the amount of liquid between the workpiece holding surface and the backside surface of the workpiece.

    摘要: A turntable with an abrasive cloth mounted thereon and a top ring positioned above the turntable are independently rotatably provided. The top ring holds a workpiece to be polished and presses the workpiece against the abrasive cloth. The turntable and the top ring are rotated to polish the surface of the workpiece to a flat mirror finish on the abrasive cloth. A rotatable brush pressed against the abrasive cloth is rotated about an axis substantially perpendicularly to the plane of the abrasive cloth, and oscillated substantially radially between radially inner and outer positions over the abrasive cloth. A cleaning solution is sprayed from a nozzle onto the abrasive cloth. The turntable has a bank along an outer circumferential edge thereto for preventing a protective solution, which is supplied to the abrasive cloth to keep the abrasive cloth wet and prevent it, from flowing off the turntable when the turntable is stationary.
