  • Polish pad conditioner with radial compensation
    Patent number: 5785585
    Abstract: An apparatus for and method of conditioning a polishing pad suitable for in-situ use, is described. The apparatus consists of a wedge-shaped conditioning plate whose width varies as a function of its length and whose exact geometry is a function of the radial effects of the polishing process effecting conditioning of the polishing pad. The conditioning plate rests on the polishing pad and is surrounded by a loose-fitting frame that holds the conditioning plate stationary with respect to the rotating polishing table, preventing lateral movement of the conditioning plate, but allowing the plate to move in the vertical direction so that it can rest flat on the polishing pad.
