Patent ID: 7019388

Claim:
A semiconductor device comprising: a die pad supported by a plurality of suspension leads; a semiconductor chip disposed over the die pad; a plurality of leads arranged around the semiconductor chip, the plurality of leads each having a first end, a second end opposite the first end, an upper surface, a lower surface, side faces, and a terminal disposed between the first end and the second end and providing an electrical connection to a wiring substrate; a plurality of wires electrically connecting the semiconductor chip with the first ends of the plurality of leads; and a resin sealing member sealing the semiconductor chip, a part of each of the plurality of leads and the plurality of wires; wherein the terminals of the plurality of leads are exposed from a back surface of the resin sealing member; wherein the upper surface, the lower surface and the side faces of the second ends of the plurality of leads are covered with resin of the resin sealing member; wherein a cut face of each of the second ends of the plurality of leads is exposed from a side face of the resin sealing member, and wherein one end of each of the plurality of suspension leads is branched in a vicinity of a corner of the resin sealing member, branched portions of said one end are exposed to side faces of the resin sealing member, and each branched portion has an upper surface, a lower surface, and side faces covered by the resin sealing member.
