Patent ID: 10453926

Abstract:
The nitride-based semiconductor device includes a carrier traveling layer 1 composed of non-doped AlxGa1-xN (0≤X<1); a barrier layer 2 formed on the carrier traveling layer 1 and composed of non-doped or n-type AlYGa1-YN (0<Y≤1, X<Y) having a lattice constant smaller than that of the carrier traveling layer 1; a threshold voltage control layer 3 formed on the barrier layer 2 and composed of a non-doped semiconductor having a lattice constant equal to that of the carrier traveling layer 1; and a carrier inducing layer 4 formed on the threshold voltage control layer 3 and composed of a non-doped or n-type semiconductor having a lattice constant smaller than that of the carrier traveling layer 1. The nitride-based semiconductor device further includes a gate electrode 5 formed in a recess structure, a source electrode 6 and a drain electrode 7.
