    摘要: A compact polishing apparatus requires less operating space than a conventional polishing apparatus generally used for polishing semiconductor wafers. The present apparatus has a swing shaft to provide a swing motion to a pressing device including a top ring member. There are three ranges of swing motion, i.e. a polishing range which is a small motion range used for polishing a wafer within the confined area of a turntable, a receiving range which is a medium motion range used for loading/unloading of a wafer in an area beyond the turntable, and a standby range which is a large motion range used for moving the top ring member to a standby or rinsing position in an area beyond the turntable. Because of the swing-based arrangement of the components in the present apparatus, isolation of critical components is easily achieved, thus resulting in low maintenance costs and long service life of the present apparatus. These advantages offer significant cost savings in the management of polishing operations.

    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.

    摘要: A drum-type polishing apparatus for producing a flat mirror polish on an object such as a semiconductor wafer, is capable of three degrees of freedom of movement of a drum member with respect to the wafer. The relative movements can be made, successively or simultaneously, at right angles to an axis of the drum, parallel to the surface of the wafer, as well as at any desired angular orientations. Combined with a follower device to provide automatic compensation for unevenness in pressing pressure applied to the wafer during polishing, the polishing apparatus offers outstanding uniformity in polishing quality and high productivity, even for large diameter wafers, with a comparatively modest investment in both facility space and equipment cost.

A spherical bearing is interposed between the top ring and the top ring drive shaft for allowing the top ring to align with the upper surface of the moving turntable. A torque transmitting mechanism is operatively coupled between the top ring and the top ring drive shaft for rotating the top ring in synchronization with the top ring drive shaft.
