Abstract:
There is provided a nitride semiconductor epitaxial substrate having a spacer structure capable of obtaining characteristics unprecedented in the prior art. In the nitride semiconductor epitaxial substrate of the present invention, a channel layer, a spacer layer, and an electron supply layer are stacked in this order. The channel layer is GaN. The spacer layer is Al a Ga 1−a N (0<a<0.5). The electron supply layer is Al x In y Ga 1−x−y N (0<x+y≤1). The spacer layer has a thickness of two molecular layers or less. Thus, adverse effects due to the existence of a conventional spacer layer are suitably suppressed.

Claim (Index 2):
The nitride semiconductor HEMT using the nitride semiconductor epitaxial substrate according to  claim 1 .
