Abstract:
A semiconductor device includes: a substrate; a p-type GaN layer that is formed above the substrate, and includes GaN containing p-type impurities; and a Ti film formed on a surface of the p-type GaN layer. The Ti film includes a Ti film containing no nitrogen and a nitrogen-containing Ti film that is less chemically active than such Ti film. The nitrogen-containing Ti film continuously surrounds an outer periphery of the Ti film containing no nitrogen in a planar view.

Claim (Index 4):
The semiconductor device according to  claim 1 ,\n wherein the p-type semiconductor layer includes: a first activation region that is in contact with the first metal; and a second activation region that is in contact with the second metal, and an acceptor ion concentration of the first activation region is higher than an acceptor ion concentration of the second activation region.
