    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 polishing apparatus 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 polishing head having at least one elastic membrane configured to form a plurality of pressure chambers for being supplied with a pressurized fluid, and a controller configured to control supply of the pressurized fluid to the pressure chambers. The controller controls supply of the pressurized fluid so that the pressurized fluid is supplied first to the pressure chamber located at a central portion of the substrate when the substrate is brought into contact with the polishing surface, and then the pressurized fluid is supplied to the pressure chamber located at a radially outer side of the pressure chamber located at the central portion of the substrate.

    摘要: There is provided a substrate polishing machine which comprises a polishing surface and a substrate carrier for holding a substrate and bringing it into contact with the polishing surface. The substrate carrier comprises a carrier body, a substrate holding member for holding a substrate with a surface of the substrate to be polished being directed towards the polishing surface. The substrate holding member is mounted on the carrier body in such a manner that the substrate holding member is movable both towards and away from the polishing surface. The substrate polishing machine further comprises a substrate holding member positioning device provided on a side of the substrate holding member opposite to that used for holding the substrate. The substrate holding member positioning device has a flexible member which defines a chamber, and which, upon introduction of a non-compressible fluid, is expanded in a direction towards the polishing surface.

    摘要: A polishing apparatus for polishing a workpiece such as a semiconductor wafer has a turntable with a polishing cloth mounted on an upper surface thereof, and a top ring for holding a workpiece and pressing the workpiece against the polishing cloth under a first pressing force to polish the workpiece. The top ring has a recess defined therein for accommodating the workpiece therein. A presser ring is vertically movably disposed around the top ring, and is pressed against the polishing 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. Relative rotation between the top ring and the presser ring is achieved during polishing.
