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 1):
A method of manufacturing a semiconductor device, comprising the steps of:\n (a) providing a semiconductor wafer having a semiconductor chip including:\n a semiconductor substrate, \n a pad electrode formed over the semiconductor substrate, and \n a conductive layer including:\n a first layer comprised of a nickel layer and formed over the pad electrode, and \n a second layer comprised of a gold layer and formed over the first layer; \n \n (b) connecting a wire comprised of copper with the conductive layer; (c) after the step (b), performing a first heat treatment to the semiconductor chip; and (d) after the step (c), sealing the semiconductor chip and the wire with a resin, and forming a sealing body, wherein a main surface of the second layer has a first region to which the wire is bonded, and a second region other than the first region, and wherein, in the second region, the sealing body is in contact with the main surface of the second layer.
