发明名称 Method for separating protective tape, and apparatus using the same
摘要 A peripheral edge of a protective tape joined to a front face of a semiconductor wafer is snagged on a needle having a sharp tip end so as to be partially separated from the front face of the semiconductor wafer; thus, a separated portion is formed. Next, an operation of joining a separating tape to a surface of the protective tape is started from the separated portion, and the protective tape is separated together with the separating tape from the front face of the semiconductor wafer with the separated portion as a starting end.
