Abstract:
A nitride semiconductor epitaxial stack structure including: a Silicon substrate; an aluminum-including nucleation layer disposed on the silicon substrate; a buffer structure disposed on the aluminum-including nucleation layer and sequentially including: a first superlattice epitaxial structure, a first GaN based thick layer disposed on the first superlattice epitaxial structure, a second superlattice epitaxial structure disposed on the first GaN based thick layer, and a second GaN based thick layer disposed on the second superlattice epitaxial structure; a channel layer disposed on the buffer structure; a barrier layer disposed on the channel layer; and a two dimensional electron gas layer disposed near an interface between the channel layer and the barrier layer, wherein the total thickness of the first GaN based thick layer and the second GaN based thick layer is more than 2 micrometers.

Claim (Index 7):
The nitride semiconductor epitaxial stack structure of  claim 1 , wherein the first superlattice epitaxial structure and/or the second superlattice epitaxial structure comprise an impurity, respectively, and the impurity comprises Fe or C.
