Patent ID: 6960823

Claim:
A semiconductor device comprising: a cross-shaped die pad supporting a semiconductor chip and being smaller in outer size than a rear surface of said semiconductor chip which is connected to said die pad with a plurality of small double-sided adhesive tapes; a wire connected to a surface electrode of said semiconductor chip; a plurality of inner leads located around said semiconductor chip, in which a silver plating layer is formed at a wire bonding area of at least one of the inner leads to which said wire is bonded, a molding resin for resin sealing said semiconductor chip; and a plurality of outer leads respectively connected to the inner leads and protruding from the molding resin, in which a lead-free metallic layer is formed on a contact surface, wherein the flat surface size of said molding resin is formed to be equal to or less than 28 mm×28 mm and the thickness thereof is formed to be 1.4 mm or less; and wherein said lead-free metallic layer formed on said outer leads is a metallic layer formed after bonding said wire to said wire bonding area of said at least one inner lead.
