Patent ID: 7728355

Claim:
A III-nitride power semiconductor device, comprising: an N-polar III-nitride body having an N-polar face; a III-nitride buffer layer on said N-polar face; a III-nitride heterojunction that includes a III-nitride barrier layer, and a III-nitride channel layer, said III-nitride heterojunction including a two-dimensional electron gas (2DEG) produced over said III-nitride barrier layer; a first power electrode disposed over said heterojunction and coupled to said 2DEG; a second power electrode disposed over said heterojunction and coupled to said 2DEG; and a gate arrangement disposed over said heterojunction between said first and said second power electrode and including a P-type III-nitride body, and a gate electrode, said P-type III-nitride body being disposed between said heterojunction and said gate electrode.
