  • Publication number: 20120160397
    Abstract: A liquid adhesive is applied to a circuit surface of a semiconductor wafer. A carrier is joined to a surface of the semiconductor wafer coated with the adhesive. A rear face of the semiconductor wafer is ground while the carrier is held. The semiconductor wafer is supported on a ring frame via a support adhesive tape. The carrier is removed from the semiconductor wafer. The adhesive tape is separated integrally with the film-like adhesive from the semiconductor wafer through joining a separation tape having a width larger than a diameter of the semiconductor wafer to the adhesive on the semiconductor wafer and then separating the separation tape.

  • Patent number: 7984737
    Abstract: In a state that a reference plane of a cutter holder, to which a cutter blade is attached, is brought into contact with a surface of a base of a supporting adhesive tape, the cutter blade cuts the supporting adhesive tape while the reference plane of the cutter holder follows the surface of the base. Herein, a cutting edge of the cutter blade passes by a joining interface between the supporting adhesive tape and a ring frame without penetrating through an adhesive layer of the supporting adhesive tape.

  • Publication number: 20110056615
    Abstract: A nipper formed of a pair of nip blocks in an open state suction-holds on nip surfaces thereof a front end of the adhesive tape that is folded back with an edge member and separated from a separator. Then, the nip block on a front end side pivots to unite the nip surfaces of the nip blocks to each other. As a result, the adhesive tape is bent inwardly and adhesive layers thereof are adhered to each other to form a tab. The nip block on a rear end side suction-holds a rear end of the cut adhesive tape. Then, the nip block on the rear end side pivots to bend the adhesive tape inwardly for forming a tab.

  • Patent number: 7849900
    Abstract: During relative and horizontal movement of a mount frame, in which a semiconductor wafer with a protective tape is supported on a ring frame through a supporting adhesive tape, and a joining member, a position of an end edge of the protective tape is detected in a non-contact manner. Based on the detection result, a joining member is stopped in the position of the end edge of the protective tape and is moved close to the semiconductor wafer to press and bring a separation tape against and into contact with an end of the protective tape. In this state, the mount frame and the joining member are relatively and horizontally moved to join the separation tape onto the protective tape. Then, the mount frame and the joining member are relatively and horizontally moved to separate the separation tape together with the protective tape from a surface of the semiconductor wafer.
