Patent ID: 8513785

Claim:
In a single mold semiconductor device having a chip mounting portion with an obverse surface on which a semiconductor chip is mounted, a suspension lead coupled to the chip mounting portion, a plurality of leads disposed around the chip mounting portion in plan view, a sealing body sealing the semiconductor chip, a portion of the suspension lead and a portion of each of the plurality of leads, each of the plurality of leads having an obverse surface facing substantially a same direction as a top surface of the sealing body and exposed from the sealing body, each of the plurality of leads having a reverse surface having an outer end portion exposed from a bottom surface of the sealing body, and each of the plurality of leads having an end surface exposed from a first side surface of the sealing body, and the plurality of leads and the suspension lead each having been separated from a lead frame by punching, said single mold semiconductor device having the improvement wherein: the suspension lead has a reverse surface of an outer end portion covered by the sealing body, an end surface of the outer end portion exposed from a second side surface of the sealing body, and an obverse surface exposed from the sealing body, and a thickness of the end surface of the suspension lead is less than a respective thickness of the end surface of each of the plurality of leads in a thickness direction of the sealing body.
