Patent ID: 7538416

Claim:
A resin molded type semiconductor device comprising: a semiconductor chip which is mounted on a die pad of a lead frame; thin metal wires which electrically connect terminals of an upper face of said semiconductor chip to inner lead portions of the lead frame; a sealing resin which seals an outer peripheral region of said semiconductor chip, said region including a thin metal wire region of the upper face of said semiconductor chip, and a lower region of said die pad; and outer lead portions which are arranged in a bottom face region of said sealing resin, wherein: said lead frame has suspension leads which support said die pad, said suspension leads have a step portion for raising a position of said die pad, and said sealing resin exists below said die pad in a thickness corresponding to a step difference of said step portion, and at least a portion of the outer periphery of the semiconductor chip extends outward from the outer periphery of said die pad, wherein said inner lead portions are arranged in the bottom face region of said sealing resin and are thicker than said suspension leads.
