Abstract:
A semiconductor device includes a conductive substrate, a channel forming layer, a first electrode, and a second electrode. The channel forming layer is located above the conductive substrate and includes at least one hetero-junction structure. The hetero-junction structure includes a first GaN-type semiconductor layer providing a drift region and a second GaN-type semiconductor layer having a bandgap energy greater than the first GaN-type semiconductor layer. A total fixed charge quantity of charges in the first GaN-type layer and the second GaN-type layer is from 0.5×10 13  to 1.5×10 13  cm −2 . The charges in the first GaN-type layer and the second GaN-type layer include charges generated by the polarization in the first GaN-type layer. Accordingly, the semiconductor device capable of improving a break-down voltage and decreasing an on-resistance is obtained.

Claim (Index 4):
The semiconductor device according to  claim 2 , further comprising:\n an electrical field easing layer that is formed of a GaN-type semiconductor layer and is located between the first electrode and the second electrode above the second GaN-type semiconductor layer; and a fourth electrode that is located above the electrical field easing layer and has an electrical potential equivalent to the third electrode, wherein the first electrode, the second electrode, the third electrode and the fourth electrode provide four terminals.
