Abstract:
A semiconductor device made of primarily nitride semiconductor materials is disclosed. The semiconductor device includes a substrate; a semiconductor stack on the substrate; electrodes of a gate, a source, and a drain each provided on the semiconductor stack, where the gate electrode contains nickel (Ni); a Si compound covering surfaces of the semiconductor stack; an aluminum oxide (Al 2 O 3 ) film covering the gate electrode exposed from the Si compound; and another Si compound covering the Al 2 O 3  film and the Si compound exposed from the Al 2 O 3  film. A feature of the semiconductor device of the invention is that the Al 2 O 3  film exposes the Si compound at least between the gate electrode and the drain electrode.

Claim (Index 1):
