    摘要: A polishing apparatus for polishing a workpiece such as a semiconductor wafer has a turntable with an abrasive cloth mounted on an upper surface thereof, and a top ring for holding a workpiece and pressing the workpiece against the abrasive cloth under a first pressing force to polish the workpiece. A guide ring is vertically movably disposed around the top ring, and pressed against the abrasive cloth under a variable second pressing force. The first and second pressing forces are variable independently of each other, and the second pressing force is determined based on the first pressing force.

    摘要: A polishing is used for polishing a substrate such as a semiconductor wafer to a flat mirror finish. The polishing apparatus includes a polishing table having a polishing surface, a substrate holding apparatus configured to hold the substrate and to press the substrate against the polishing surface, and a controller. The substrate holding apparatus includes an elastic membrane configured to form a substrate holding surface which is brought into contact with the substrate, a carrier provided above the elastic membrane, at least one pressure chamber formed between the elastic membrane and the carrier, and an infrared light detector configured to measure thermal energy from the elastic membrane. The controller calculates an estimate value of a temperature of the elastic membrane using a measured value of the infrared light detector.

    摘要: A substrate holding apparatus prevents a substrate from slipping out and allows the substrate to be polished stably. The substrate holding apparatus has a top ring body for holding and pressing a substrate against a polishing surface, and a retainer ring for pressing the polishing surface, the retainer ring being disposed on an outer circumferential portion of the top ring body. The retainer ring includes a first member made of a magnetic material and a second member having a magnet disposed on a surface thereof which is held in abutment against the first member.

    摘要: A substrate holding apparatus has a substrate holder body with a substrate holding side facing a polishing surface and holding a substrate on the substrate holding side and a retainer ring fixedly secured to the substrate holder body. The retainer ring is arranged to surround an outer periphery of the substrate held by the substrate holder body so that the retainer ring engages with the polishing surface radially outside the substrate as the polishing of the substrate is effected. The substrate holder body is provided with a membrane having inside and outside surfaces. The inside surface cooperates with a surface of the substrate holder body to define a fluid pressure chamber to which a fluid pressure is applied. The outer surface engages with the substrate held by the substrate holder body.

    摘要: A polishing apparatus can improve the uniformity of thickness within a workpiece or reduce thickness variation between serially polished workpieces. The polishing apparatus comprises a polishing unit having a polishing tool for providing a polishing surface and a workpiece holding device for holding the workpiece. A polishing solution or liquid supplying device is provided for supplying a polishing solution or liquid into a polishing interface between the surface of the workpiece and the polishing surface. A temperature of the polishing interface is controlled according to at least an ambient temperature of a polishing space surrounding the polishing unit, as a variable parameter.

    摘要: A polishing apparatus for polishing a workpiece to a flat mirror finish includes a turntable with a polishing cloth attached to an upper surface thereof, and a top ring for holding a workpiece thereon and pressing the workpiece against the polishing cloth to polish the workpiece. A retainer ring or a presser ring is disposed around the top ring. The retainer ring or the presser ring is vertically movable independently of the top ring, and pressed against the polishing cloth by a pressing mechanism. A stabilizing mechanism is disposed between an inner circumferential surface of the retainer ring or the presser ring, and an outer circumferential surface of the top ring, for holding the top ring substantially stabilized within the retainer ring or the presser ring.
