Patent ID: 7528014

Claim:
A manufacturing method of a semiconductor device comprising the steps of: (a) providing a lead frame having a first suspension lead, a second suspension lead intersecting with the first suspension lead, a die pad comprised of a part of the first suspension lead, a part of the second suspension lead and an intersecting point comprised of the part of the first suspension lead and the part of the second suspension lead, and a plurality of leads arranged around the die pad; (b) arranging a first adhesive tape on the first suspension lead of the die pad and the intersecting point of the die pad wherein the first adhesive tape is comprised of a base material and an adhesive layer; (c) arranging each of a plurality of second adhesive tapes on the second suspension lead of the die pad such that the intersecting point is arranged between the plurality of second adhesive tapes wherein each of the plurality of second adhesive tapes is not arranged on the intersecting point of the die pad to thereby avoid overlapping said first adhesive tape with said second adhesive tapes, wherein a size of each of the plurality of second adhesive tapes is smaller than that of the first adhesive tape, and wherein each of the second adhesive tapes is comprised of the base material and the adhesive layer; (d) disposing a semiconductor chip over the die pad through the first and second adhesive tapes, the semiconductor chip having a main surface, a rear surface opposed to the main surface, and a plurality of surface electrodes formed on the main surface; (e) electrically connecting the plurality of surface electrodes of the semiconductor chip with the plurality of inner leads of the lead frame through a plurality of wires, respectively; and (f) sealing the die pad, the semiconductor chip and the plurality of wires with a molding resin such that a part of each of the plurality of leads is exposed from the molding resin, wherein a first one of the second adhesive tapes is separated from a second one of the second adhesive tapes by the first adhesive tape.
