摘要: A workpiece holding device enables stable polishing to be performed without sacrificing the structural strength of a top ring or the space necessary for machining a through hole or implanting engaging pins while allowing close contact to be made between a workpiece to a polishing cloth on a polishing tool. The top ring includes a top ring member having a holder plate for holding the workpiece on a front surface and a cover plate attached to a back surface of the holder plate by engaging a depression section formed on a back surface of the holder plate with a protrusion section formed on a front surface of the cover plate. A curved surface bearing unit provided between an end portion of a drive shaft and a back surface of the cover plate couples the drive shaft and the top ring member while permitting motion of the top ring member relative to the polishing tool. At least a portion of the curved surface bearing unit is positioned within the depression section.

摘要: A polishing apparatus is employed to polish an object to be polished by urging the surface of the object to be polished against the surface of a polishing cloth and causing a relative movement therebetween, while supplying a polishing liquid into an area between the object to be polished and the polishing cloth. A plurality of nozzles spray respective fluid jets to strike against the surface of the cloth. The plurality of nozzles include more than one type of nozzle which vary flow velocity, flow rate, angle of spray, and cross-sectional configuration of a jet. The plurality of nozzles have axes positioned at a location at different distances from the rotation axis of the polishing cloth.

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.
