Abstract
A method of peeling a protective tape, includes the steps of mounting a wafer on a stage, the wafer having the protective tape adhered thereto so that the protective tape overlaps only a portion of a notch of the wafer, attaching a peeling adhesive tape to the protective tape, projecting a lift pin from the stage so that the portion of the protective tape which overlaps the notch is raised by a top surface of the lift pin, and with the protective tape raised by the lift pin, pulling the peeling adhesive tape so as to peel the protective tape from the wafer. The top surface of the lift pin has a shape that allows the top surface to raise the portion of the protective tape which overlaps the notch.
