Abstract:
1. An apparatus for joining an adhesive tape to a back face of a semiconductor wafer after a process of working the back face of the semiconductor wafer, the apparatus comprising: a holding member for holding the semiconductor wafer including a first face having a pattern formed thereon and a second face of an opposite side, in a state where the first face of the semiconductor wafer is directed upward; a ring frame, including a first face on which the adhesive tape is joined in advance and a second face of an opposite side, disposed below the semiconductor wafer with the first face of the ring frame on which the adhesive tape is joined being directed downward such that an adhesion face of the adhesive tape faces the second face of the semiconductor wafer, the ring frame being aligned with the semiconductor wafer; and a ring frame lifting mechanism for holding the second face of the ring frame, and moving the ring frame upward/downward so as to join the adhesive tape joined to the ring frame to the second face of the semiconductor wafer, wherein the holding member is provided with a drop preventing mechanism for preventing the semiconductor wafer from dropping until the adhesive tape is joined to the semiconductor wafer held.
