Claim Text:
1. A semiconductor device, comprising: a chip mounting part; a first semiconductor chip that has a first principal plane and a second principal plane being an opposite side plane to the first principal plane and is mounted over the chip mounting part in a direction in which the second principal plane faces the chip mounting part; and a second semiconductor chip that has a third principal plane and a fourth principal plane being an opposite side plane to the third principal plane and a part of which is mounted over the first semiconductor chip in a direction in which the third principal plane faces the first principal plane, wherein in plane view, the chip mounting part has a notch part and a part of the second semiconductor chip overlaps the notch part, and further wherein the semiconductor device comprises: a first electrode pad located in a portion of the first principal plane of the first semiconductor chip that does not overlap the second semiconductor chip; a second electrode pad located in a region of the third principal plane of the second semiconductor chip that overlaps the notch part; a first bonding wire whose one end couples to the first electrode pad; and a second bonding wire whose one end couples to the second electrode pad.
