Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a lead frame including a chip mounting area and a plurality of leads; (b) mounting a semiconductor chip over the chip mounting area of the lead frame, the semiconductor chip having a plurality of electrode pads; (c) coupling the leads and the electrode pads of the semiconductor chip via a plurality of bonding wires; and (d) sealing the semiconductor chip, the bonding wires and a portion of each of the leads with a resin, wherein the bonding wires include a first bonding wire coupling a first lead of the leads with a first electrode pad of the electrode pads, and a second bonding wire coupling the first lead with a second electrode pad of the electrode pads; wherein a diameter of the second bonding wire is smaller than that of the first boding wire; and wherein, in the step (d), the resin is supplied from the first bonding wire side than the second bonding wire side toward the second bonding wire side.
