Abstract:
1. A semiconductor device comprising: a semiconductor chip having an obverse surface over which a plurality of electrode pads are arranged; a chip mounting portion having an obverse surface over which the semiconductor chip is mounted and a reverse surface opposite the obverse surface; a suspension lead integrated with the chip mounting portion; a plurality of leads disposed around the chip mounting portion; a plurality of wires connecting the plurality of electrode pads with the plurality of leads, respectively; and a sealing body having a top surface, a bottom surface opposite the top surface, and a plurality of side surfaces in a thickness direction thereof, and sealing the semiconductor chip, a part of the suspension lead, and parts of the plurality of leads, wherein a reverse surface of each of the plurality of leads is exposed from the bottom surface of the sealing body, wherein, in a top surface view of the sealing body, the suspension lead has an end portion projected from a part of a side surface of the plurality of side surfaces of the sealing body, wherein the end portion of the suspension lead has a top surface exposed from the sealing body and a bottom surface sealed with the sealing body, wherein the end portion of the suspension lead is formed more thinly than a thickness of each of the plurality of leads, wherein the sealing body has a chamfered corner portion, and wherein the end portion of the suspension lead is projected from the chamfered corner portion of the sealing body.
