Patent ID: 8399912

Claim:
A III-nitride power semiconductor device including a first high electron mobility transistor (HEMT) comprising: a first III-nitride layer; a second III-nitride layer forming a heterojunction with said first III-nitride layer; a field nitride layer and a gate nitride on said second III-nitride layer; a gate metal on said gate nitride; a plurality of interconnect metal layers including a top metal layer and a bottom metal layer on said second III-nitride layer, said bottom metal layer including a source contact, a drain contact, and a gate contact on said gate metal; a plurality of vias interconnecting said plurality of interconnect metal layers through a plurality of dielectric layers to connect said source contact, said drain contact, and said gate contact to said top metal layer; a solderable front metal on said top metal layer, said solderable front metal comprising spaced elongated digits configured for external circuit connection through solder bars.
