    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: A polishing apparatus for polishing a substrate comprises a polishing table having a polishing surface, and a substrate holding apparatus for holding a substrate to be polished and pressing the substrate against the polishing surface. The substrate holding apparatus comprises a vertically movable top ring body for holding a substrate, and a fluid supply source for supplying a fluid under a positive pressure or a negative pressure to a hermetically sealed chamber which is defined in the top ring body so as to control pressure under which the substrate is pressed against the polishing surface. The substrate holding apparatus further comprises a measuring device disposed in a fluid passage interconnecting the hermetically sealed chamber and the fluid supply source for measuring a flow rate of the fluid in the fluid passage.

    摘要: The present invention relates to a substrate holding apparatus for holding a substrate to be polished and pressing the substrate against a polishing surface. The substrate holding apparatus comprises a top ring body for holding a substrate, an elastic pad for being brought into contact with the substrate, and a support member for supporting the elastic pad. The substrate holding apparatus further comprises a contact member mounted on a lower surface of the support member and disposed in a space formed by the elastic pad and the support member. The contact member has an elastic membrane for being brought into contact with the elastic pad. A first pressure chamber is defined in the contact member, and a second pressure chamber is defined outside of the contact member. The substrate holding apparatus further comprises a fluid source for independently supplying a fluid into, or creating a vacuum in, the first pressure chamber and the second pressure chamber.

    摘要: There is disclosed a polishing apparatus comprising: a polishing table having a first axis and a counterweight provided on the polishing table. The polishing table is adapted to be subjected to a circular orbital motion in which the first axis of the polishing table is rotated about an orbit center axis while the orientation of the polishing table is kept substantially constant. The counterweight cancels a centrifugal force generated by the circular orbital motion of the polishing table.
