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 10):
The semiconductor device according to  claim 1 ,\n wherein the Si compound includes a first insulating film in contact with the semiconductor stack and a second insulating film provided on the first insulating film, the first insulating film and the second insulating film being made of silicon nitride (SiN), and wherein the second insulating film covers the source electrode and the drain electrode.
