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 11):
A process of forming a semiconductor device, comprising steps of:\n epitaxially growing a semiconductor stack on a substrate; forming electrodes of a source, a gate, and a drain by steps of:\n deposing a first insulating film made of silicon nitride (SiN) on the semiconductor stack by a low pressure chemical vapor deposition (LPCVD) technique, \n forming the source electrode and the drain electrode so as to be in direct contact with the semiconductor stack through respective openings formed in the first insulating film, \n covering the source electrode, the drain electrode, and the first insulating film by a second insulating film made of silicon nitride (SiN) formed by a plasma-assisted chemical vapor deposition (p-CVD) technique, the first insulating film and the second insulating film constituting the Si compound, and \n forming a gate electrode so as to be in direct contact with the semiconductor stack through an opening formed in the Si compound, the gate electrode including nickel (Ni); \n covering the gate electrode and the Si compound by an aluminum oxide (Al 2 O 3 ) film; partially removing the Al 2 O 3  film at least between the gate electrode and a drain electrode; and depositing another Si compound so as to cover the Al 2 O 3  film and the Si compound exposed from the Al 2 O 3  film, the another Si compound containing Si atoms.
