    Abstract: Provided are a GaN epitaxial substrate having an improved yield, a semiconductor device using such GaN epitaxial substrate, and methods for manufacturing the GaN epitaxial substrate and the semiconductor device. The GaN epitaxial substrate manufacturing method has a first GaN layer forming step of epitaxially growing a first GaN layer on a base substrate; a recessed section forming step of forming a recessed section on an upper surface of the base substrate after the first GaN layer forming step; and a second GaN layer forming step of epitaxially growing a second GaN layer on the first GaN layer after the recessed section forming step. Thus, generation of cracks is suppressed and the yield is improved.
