Abstract:
To provide a semiconductor device having improved reliability. A method of manufacturing the semiconductor device includes connecting a wire comprised of copper with a conductive layer formed on the pad electrode of a semiconductor chip, heat treating the semiconductor chip, and then sealing the semiconductor chip and the wire with a resin.

Claim (Index 9):
A method of manufacturing a semiconductor device, comprising the steps of:\n (a) providing a semiconductor chip, the semiconductor chip including a pad electrode and a conductive layer formed over the pad electrode and connected with the pad electrode, the conductive layer including a first metal layer and a second metal layer formed over the first metal layer and contacted with the first metal layer, the pad electrode being comprised of a material softer than the first metal layer, the first metal layer being comprised of nickel as a main component, the second metal layer being comprised of gold as a main component, and the second metal layer being an uppermost layer of the conductive layer; (b) after the step (a), electrically connecting a wire to the pad electrode of the semiconductor chip via the conductive layer, the wire being comprised of copper as a main component; (c) after the step (b), baking the semiconductor chip and thereby forming an oxide film in a region which is of a surface of the second metal layer configuring the conductive layer and with which the wire is not in contact; and (d) after the step (c), sealing the semiconductor chip and the wire with a resin, and bringing the resin into contact with the oxide film.
