A semiconductor device having a molded package includes a semiconductor chip, a thick-film lead electrode to which the semiconductor chip is die-bonded, a thin-film lead electrode having a thickness smaller than that of the thick-film lead electrode, a wire which electrically connects the semiconductor chip to the thin-film lead wire, and a molding material in which the semiconductor chip and the wire are encapsulated. A portion of a lower surface of the thick-film lead electrode is exposed at a package lower surface as a heat dissipating electrode. A portion of an upper surface of the thin-film lead electrode is exposed at a package upper surface as an input/output electrode. A portion of an upper surface of the thick-film lead electrode is exposed at the package upper surface as a grounding electrode.
