  • Patent number: 7935217
    Abstract: A bevel unit comprises CCDs and processing liquid nozzles, and the CCDs take an image of a circumferential edge surface of a substrate. An image processing part detects the distances between the circumferential edge surface of the substrate and the processing liquid nozzles by image processing the signals from the CCDs. A control unit compares thus detected distances between the circumferential edge surface of the substrate and the processing liquid nozzles with set distances from the circumferential edge surface of the substrate to the processing liquid nozzles which are set in a recipe so as to be a desired rim etching width, and calculates an amount of displacement between the detected distances and the set distances. In accordance with the amount of displacement, the control unit activates motors and accordingly positions the bevel unit.

  • Patent number: 7879180
    Abstract: Disclosed are a polishing device and polishing method for forming a wafer with high flatness using a CMP process. For the polishing of the wafer, a polishing device including a chuck section and a polishing member having a needle member is used. In the polishing, the wafer is fixed on the chuck section and then, a working fluid containing no abrasive grains is supplied to a wafer surface as well as the needle member is pressed against the wafer surface and is caused to rapidly vibrate. By doing so, the needle member tip is caused to vibrate to rub the wafer surface, thereby performing the polishing. As a result, dishings due to asperities on the wafer surface or scratches extending over a wide range are prevented from occurring, so that the wafer with high flatness can be obtained.
