Abstract:
A process of forming an epitaxial substrate is disclosed, where the epitaxial substrate includes a nucleus forming layer made of aluminum nitride (AlN) grown on a substrate made of silicon carbide (SiC). The process includes steps of: (1) first measuring the first reflectivity R 0  of a surface of the SiC substrate, (2) growing the nucleus forming layer made of AlN as measuring second reflectivity R 1  of a grown surface of the AlN nucleus forming layer, and (3) ending the growth of the AlN nucleus forming layer when a ratio R 1 /R 0  of the reflectivity enters a preset range.

Claim (Index 8):
The process according to  claim 1 ,\n further including steps of: growing a channel layer made of gallium nitride (GaN) on the nucleus forming layer; and growing a barrier layer on the channel layer.
