Patent ID: 7393757

Claim:
A method for joining a dicing tape to a semiconductor wafer to which a supporting member is joined via a both-faced adhesive sheet, fixing the resultant to a dicing frame, and separating the semiconductor wafer integrally with the dicing frame from the supporting member, the method comprising the step of: separating the semiconductor wafer integrally with the dicing frame from the supporting member while weakening adhesive strength of the both-faced adhesive sheet without restricting the both faced adhesive sheet in the thickness direction, wherein in the step, the semiconductor wafer and the dicing frame are lifted via the supporting member by holding the supporting member in a posture that the surface of the supporting member faces upward, and by weakening adhesive strength of the both-faced adhesive sheet in this state, the semiconductor wafer and the dicing frame are integrally separated from the supporting member by dead loads of the semiconductor wafer and the dicing frame.
