Claim Text:
1. A semiconductor device comprising: a first electrode; a second electrode; a first semiconductor region of a first conductivity type located between the first electrode and the second electrode and is in contact with the first electrode; a second semiconductor region of a second conductivity type that is selectively located between the first semiconductor region and the second electrode; a plurality of contact regions located between the second semiconductor region and the second electrode, each contact region being in contact with the second semiconductor region and the second electrode; a plurality of third semiconductor regions of a second conductivity type located between the second electrode and the first semiconductor region and in contact with the second electrode; and a wiring in contact with the second electrode via a bonding portion, the bonding portion of the wiring bonded to the second electrode at a location between the contact regions adjacent to the third semiconductor region.
