Claim Text:
1. A III-Nitride semiconductor device comprising: a first III-Nitride layer; a second III-Nitride layer over said first III-Nitride layer; a 2DEG layer formed by the interface between said first and second III-Nitride layers; a source contact connected to said first III-Nitride layer; a drain contact laterally spaced from said source contact and connected to said first III-Nitride layer, a gate contact coupled to said first III-Nitride layer and disposed laterally between said source and drain contacts; a conductive field plate disposed between said gate and drain contacts and connected to said source contact to reduce the electric field between said gate and drain contacts when said 2DEG layer is non-conductive, wherein said conductive field plate having a thickness is formed from a first portion of a gate electrode, and wherein said gate contact having said thickness is formed from a second portion of said gate electrode, said first and second portions of said gate electrode having a coplanar top surface, said second portion being physically separated and laterally spaced from said first portion.
