Abstract:
A nitride semiconductor device includes: an electron transit layer including Ga x In 1-x N (0<x≤1); an electron supply layer formed on the electron transit layer and including Al y In 1-y N (0<y≤1); a gate insulating film formed to pass through the electron supply layer to contact the electron transit layer; and a gate electrode facing the electron transit layer with the gate insulating film interposed therebetween, wherein, in the electron transit layer, a portion contacting the gate insulating film and a portion contacting the electron transit layer are flush with each other.

Claim (Index 13):
A nitride semiconductor device comprising:\n an electron transit layer including Ga x In 1-x N (0<x\u22641); an electron supply layer formed on the electron transit layer and including Al a Ga b In c N (0\u2264a\u22641, 0\u2264b\u22641, 0\u2264c\u22641 and a+b+c=1); a gate insulating film formed to pass through the electron supply layer to contact the electron transit layer; a gate electrode facing the electron transit layer with the gate insulating film interposed therebetween; a trench formed in the electron supply layer to expose the electron transit layer; and a nonconductive spacer layer formed on the electron supply layer, wherein the gate insulating film is formed in the trench, wherein the trench is formed to expose the electron transit layer through the spacer layer and the electron supply layer, wherein the gate insulating film is formed along an inner wall of the trench and a surface of the electron transit layer, and wherein, in the gate insulating film, a portion formed along the inner wall of the trench is thicker than a portion formed along the surface of the electron transit layer.
