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 45):
The manufacturing method as claimed in  claim 24 , wherein the forming the plurality of initial nuclei made of the second group III nitride semiconductor on the substrate, the forming the plurality of initial nuclei made of the second group III nitride semiconductor on the substrate and the gas-phase etching, and the forming the third group III nitride semiconductor layer are repeated more than once after the forming the third group III nitride semiconductor layer.
