Abstract:
A manufacturing method for a group III nitride semiconductor substrate is provided with a first step of forming a second group III nitride semiconductor layer on a substrate; a second step of forming a protective layer on the second group III nitride semiconductor layer; a third step of selectively forming pits on dislocation portions of the second group III nitride semiconductor layer by gas-phase etching applied to the protective layer and the second group III nitride semiconductor layer; and a fourth step of forming a third group III nitride semiconductor layer on the second group III nitride semiconductor layer and/or the remaining protective layer so as to allow the pits to remain.

Claim (Index 27):
The manufacturing method as claimed in  claim 26 , wherein the first group III nitride semiconductor layer is an AlN layer.
