Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a wiring substrate having a plurality of second electrode pads formed over a main surface thereof; (b) mounting a semiconductor chip over the wiring substrate, the semiconductor chip having over a main surface thereof a plurality of first electrode pads formed as exposed areas of a metallic film which contains aluminum (Al) as a main component; and (c) connecting the first electrode pads and the second electrode pads with each other through electrically conductive wires which contain gold (Au) as a main component, the step (c) comprising the steps of: (d) wherein palladium (Pd) is contained in the electrically conductive wires, and (e) wherein the step (c1) is carried out in a state in which the temperature of the main surface of the semiconductor chip is not higher than 200° C.
