  • Patent number: 7291057
    Abstract: A method of polishing substrates enables the size of a polishing table to be reduced. A surface of a substrate to be polished is brought into contact with a polishing surface of a polishing table in such a manner that a portion of the surface of the substrate extends outwardly from an outer periphery of the polishing surface. The substrate is rotated about its center axis while keeping its surface in contact with the polishing surface of the polishing table. The attitude of the substrate carrier is controlled so that the surface of the substrate is kept parallel with the polishing surface of the polishing table during a polishing operation.

  • Publication number: 20070238395
    Abstract: A substrate polishing apparatus wherein a semiconductor substrate is held by a top ring 10-2 or 11-2 and is pressed against a polishing surface of a polishing table 10-1 or 10-2. A surface to be polished of the semiconductor substrate is polished by a relative movement between the semiconductor substrate and the polishing surface. The apparatus includes a pressing force changing mechanism for changing a pressing force for pressing the semiconductor substrate, a relative movement seed changing mechanism for changing the number of revolutions of the top ring and/or the polishing table, and a control mechanism. The control mechanism performs the polishing through plural polishing processes on the polishing table 10-1 or 10-2 while changing the pressing force and the number of revolutions.
