Patent ID: 8890334

Claim:
A semiconductor device, comprising: a first semiconductor chip having a first front side main surface and a first back side main surface, and having a first bonding pad over the first front side main surface; a second semiconductor chip having a second front side main surface and a second back side main surface, disposed such that the second back side main surface faces the first front side main surface of the first semiconductor chip, and having a second bonding pad over the second front side main surface; first and second external terminals disposed so as to be closer to the first front side main surface of the first semiconductor chip than to the second front side main surface of the second semiconductor chip; a first bonding wire for coupling the first bonding pad with the first external terminal; and a second bonding wire for coupling the second bonding pad with the second external terminal, wherein the loop height of the first bonding wire is larger than the loop height of the second bonding wire.
