Patent ID: 7172950

Claim:
A method for manufacturing semiconductor chips in which a semiconductor wafer, having a surface segmented by streets and formed with a plurality of circuits, is divided into individual circuit-based semiconductor chips, the method comprising: a support substrate integration step of bonding a front surface of a semiconductor wafer to a light-transmissive support substrate through an adhesive layer having an adhesion force that is reduced upon exposure to light radiation, thereby exposing a back surface of the semiconductor wafer; a grinding step of resting the semiconductor wafer integrated with the support substrate on a chuck table of a grinding device and grinding the back surface of the semiconductor wafer; after the grinding step, performing a tape bonding step of bonding a tape on the back surface of the semiconductor wafer while the semiconductor wafer is integrated with the support substrate and bonding a frame on a periphery of the tape; after the tape bonding step, performing a re-bonding step of applying light radiation to the adhesive layer from a side of the support substrate to thereby reduce the adhesion force of the adhesive layer, and removing the support substrate and adhesive layer from the front surface of the semiconductor wafer to thereby support the semiconductor wafer by the tape and the frame; and a dicing step of resting the semiconductor wafer supported by the tape and the frame on a chuck table of a dicing apparatus and cutting along the streets to segment the semiconductor wafer into the individual semiconductor chips.
