Patent ID: 7598604

Claim:
A semiconductor device, comprising: a first semiconductor element including an electrode forming surface having a first electrode pad thereon; a second semiconductor element including an electrode forming surface having a second electrode pad thereon, the electrode forming surface of the second semiconductor element bonding to the electrode forming surface of the first semiconductor element via an adhesive layer so that the first and second electrode pads expose, respectively; a metal circuit board having a first connection terminal and a second connection terminal arranged outside the first and second semiconductor elements, the first connection terminal connecting to the first electrode pad via a first bonding wire and the second connection terminal connecting to the second electrode pad via a second bonding wire; and a sealing material sealing the first and second semiconductor elements and the metal circuit board so that parts of the first and second connection terminals expose, wherein the first and second connection terminals each have, an outside connection terminal of a thickness substantially corresponding to a total thickness of the first and second semiconductor elements, and an inside connection terminal formed continuously from the outside connection terminal, the inside connection terminal having a thickness thinner than the thickness of the outside connection terminal, and the first and second bonding wires are accommodated within the total thickness of the first and second semiconductor elements.
