  • Patent number: 7223319
    Abstract: A semiconductor manufacturing apparatus includes: a peeling mechanism to peel a pressure sensitive adhesive (PSA) tape from a semiconductor wafer constituted by a plurality of semiconductor chips which are separated therefrom, the semiconductor wafer having an element formation surface to form an element thereon and a rear surface opposite to the element formation surface, the PSA tape adhering to the element formation surface of the semiconductor wafer, each of the semiconductor chips having an adhesive layer formed on the rear surface; wherein the peeling mechanism has a sucking section which have a porous member to hold the semiconductor wafer by suction, the porous member being segmented into at least two sucking areas in the direction in which the PSA tape is peeled.
    Type: Grant
    Filed: March 25, 2004
    Date of Patent: May 29, 2007
    Assignees: Kabushiki Kaisha Toshiba, Lintec Corporation
    Inventors: Tetsuya Kurosawa, Shinya Takyu, Kinya Mochida, Kenichi Watanabe
  • Patent number: 7060532
    Abstract: A manufacturing method of a semiconductor device includes: providing a groove having a thickness equal to or larger than a finishing thickness on a first surface of a semiconductor wafer on which a semiconductor element is formed; affixing a PSA tape onto the first surface of the semiconductor wafer in which the groove is formed; reducing the thickness of the semiconductor wafer by processing a second surface opposite to the first surface of the semiconductor wafer onto which the PSA tape is affixed, so as to separate the semiconductor wafer into a plurality of semiconductor chips on which the semiconductor element is formed; affixing an adhesive layer onto an entire rear surface of the separated semiconductor wafer; cutting the adhesive layer so as to separate the adhesive layer for each of the semiconductor chips; and peeling off the PSA tape from the semiconductor wafer while fixing the semiconductor wafer under suction by use of a porous member segmented into at least two sucking areas.
