  • Patent number: 7335578
    Abstract: A semiconductor wafer (W) where circuits are formed in the area divided by streets is split into semiconductor chips having individual circuits. By interposing an adhesive sheet, whose adhesive force is lowered by stimulation, between the semiconductor wafer (W) and the support plate (13), the front side of the semiconductor wafer (W) is adhered to the support plate (13), thereby exposing the rear face (10) of the semiconductor wafer (W). The rear face (10) of the semiconductor wafer (W) with the support plate (13) is ground. After the grinding is finished, the semiconductor wafer (W) held with the rear face (10) up is diced into semiconductor chips (C). The adhesive sheet is given stimulus to lower the adhesive force and the semiconductor chips (C) are removed from the support plate (13). The semiconductor wafer and semiconductor chips are always supported by the support plate, avoiding damage and deformation.

  • Patent number: 7172950
    Abstract: In manufacturing thinned semiconductor chips by grinding a semiconductor wafer supported on a rigid support substrate, in order to remove the semiconductor wafer or semiconductor chips from the support substrate without damage to the semiconductor wafer or semiconductor chips, a semiconductor wafer at its surface is bonded on a light-transmissive support substrate through an adhesive layer having an adhesion force that is reduced upon exposure to light radiation, thereby exposing the back surface of the semiconductor wafer. A tape is bonded to the backside of the semiconductor wafer integrated with the support substrate after grinding, wherein the tape is supported at the periphery. Before or after bonding of the tape, light radiation is applied to the adhesive layer at a side close to the support substrate to reduce the adhesion force in the adhesion layer.
