Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a first semiconductor chip having a first electrode and a second electrode on a first surface and having a third electrode on a second surface that is opposite to the first surface;
a second semiconductor chip having a fourth electrode and a fifth electrode on a third surface and having a sixth electrode on a fourth surface that is opposite to the third surface;
a first electrode plate bonded to the second electrode of the first semiconductor chip by a first bonding material;
a second electrode plate bonded to the sixth electrode of the second semiconductor chip by a second bonding material; and
a third electrode plate placed between the first semiconductor chip and the second semiconductor chip and having a thickness in a direction perpendicular to longitudinal directions of the first semiconductor chip and the second semiconductor chip, the thickness including a first thickness and a second thickness with the first thickness being thinner than the second thickness,
wherein one surface of the third electrode plate having the first thickness is bonded to the fifth electrode of the second semiconductor chip by a third bonding material, and another surface of the third electrode plate having the first thickness is bonded to the third electrode of the first semiconductor chip by a fourth bonding material,
wherein the third electrode plate having the first thickness overlaps with the first semiconductor chip and the second semiconductor chip as viewed along the direction perpendicular to the longitudinal directions of the first semiconductor chip and the second semiconductor chip, and
wherein the thickness of the third electrode plate includes a third thickness that gradually increases from a first area of the third electrode having the first thickness toward a second area of the third electrode having the second thickness.
