Abstract:
1. A semiconductor wafer mounting method of mounting a semiconductor wafer, which has a surface with protruding electrodes formed thereon, with a support board on a supporting adhesive tape joined to a ring frame by inserting a reinforcing adhesive sheet between the surface of the semiconductor wafer with protruding electrodes formed thereon and the supporting adhesive tape, the method comprising: drawing the adhesive tape and joining the adhesive tape to the ring frame, and thereafter mounting the semiconductor wafer on the adhesive tape by inserting the adhesive sheet having, an outer shape equal to or smaller than that of the semiconductor wafer between the semiconductor wafer and the adhesive tape, the semiconductor wafer being joined to the supporting board via a two-layered adhesive layer with the surface of the semiconductor wafer with the protruding electrodes formed thereon being joined to the adhesive layer in a non-cured state.
