    摘要: A pressure control system is used for eliminating individual differences of a plurality of pressure controllers used for controlling pressures of a plurality of pressure-controlled sections. The pressure control system includes a plurality of pressure controllers for supplying a pressurized fluid to a plurality of pressure-controlled sections, a master pressure controller for supplying a pressurized fluid having a reference pressure, a plurality of calibration chambers corresponding to the pressure controllers. The pressure control system further includes differential-pressure detecting devices provided in the calibration chambers to detect a differential pressure between the pressurized fluid supplied from the master pressure controller and the pressurized fluid supplied from the pressure controller, and an arithmetic device configured to receive a signal from the differential-pressure detecting device and adjust an output of the pressure controller so that the above differential pressure becomes zero or approximately zero.

    摘要: The present invention relates to a substrate holding apparatus for holding a substrate (W) such as a semiconductor wafer in a polishing apparatus for polishing the substrate to a flat finish. A substrate holding apparatus according to the present invention comprises a top ring body (2) having a receiving space therein, and a vertically movable member (206) which is vertically movable within the receiving space in the top ring body. An abutment member (209) having an elastic membrane is attached to a lower surface of the vertically movable member. The elastic membrane (291) of the abutment member comprises an abutment portion (291b), having a flange (291a) projecting outwardly, brought into direct or indirect contact with the substrate, and a connecting portion (291c) extending upwardly from a base portion (291d) of the flange of the abutment portion and being connected to the vertically movable member. The connecting portion is made of a material having a flexibility higher than the abutment portion.

    摘要: A polishing apparatus has a polishing table having a polishing surface, a carrier for carrying a plate-like member and bringing the plate-like member into contact with the polishing surface, and a dresser including a dressing tool adapted to be brought into contact with the polishing surface to dress or normalize the polishing surface. The carrier is movable along a first path between a work position for bringing into contact the plate-like member with the polishing surface and a rest position. The dresser is movable along a second path between a work position for bringing the dressing tool into contact with the polishing surface and a rest position. The first and second paths have a common overlapping area. A contact prevention device is provided to prevent the carrier and the dresser from coming into contact with each other. An actuator is provided to bring the plate-like member into a condition that a predetermined area of the surface of the plate-like member extends beyond a peripheral edge of the polishing surface.
