Patent ID: 7507606

Claim:
A method of manufacturing a semiconductor device comprising the steps of: (a) providing a lead frame formed with a plurality of patterns, wherein each of the plurality of patterns has a die pad and a plurality of leads arranged around the die pads; (b) mounting a plurality of semiconductor chips over the plurality of die pads, respectively; (c) electrically connecting each of the plurality of semiconductor chips and a corresponding plurality of leads through a plurality of wires, respectively; (d) after the step (c), clamping a part between the plurality of patterns adjacent thereto by an upper molding die and a lower molding die, and injecting resin into a plurality of cavities through a connecting portion to form a plurality of resin sealing members, wherein the plurality of cavities and the connecting portion are formed on one of the upper molding die and the lower molding die; wherein the plurality of cavities are corresponding to the plurality of patterns, respectively; wherein the connecting portion is formed between the plurality of cavities adjacent thereto; wherein the connecting portion is not clamped by the upper molding die and the lower molding die; wherein one of the plurality of resin sealing members is connected to another resin sealing member via a jointing portion; and wherein the jointing portion is formed at a portion corresponding to the connecting portion; and (e) after the step (d), cutting the lead frame and the plurality of resin sealing members with a dicer to divide the plurality of resin sealing members into individual pieces.
