Patent ID: 8659129

Claim:
A semiconductor device comprising: a semiconductor chip; a die pad having a chip mount surface for mounting the semiconductor chip, wherein the die pad has a first end and a second end; a first lead having an end part electrically connected to the semiconductor chip; a thermosetting resin part for securing the end part of the first lead to the first end of the die pad; and a thermoplastic resin part for sealing the semiconductor chip, the die pad, and the thermosetting resin part, wherein the thermosetting resin part overlaps a part of at least one of the chip mount surface and side faces of the die pad, the part being adjacent to the first lead, wherein the die pad and the first lead are separate members, wherein the thermosetting resin part is partially covering the die pad such that the second end of the die pad is free from the thermosetting resin part.
