Abstract:
A nitride semiconductor device is disclosed. The semiconductor device includes a semiconductor stack with a top layer containing gallium (Ga) and nitrogen (N), electrodes of a source, a gate and a drain provided on the semiconductor stack, and a silicon nitride (SiN) film provided on the GaN layer between the drain electrode and the gate electrode but apart from the gate electrode. The SiN film has a silicon rich composition with a composition ratio of Si/N that is greater than 3/4 and substantial oxygen contents.

Claim (Index 3):
The nitride semiconductor device according to  claim 2 ,\n further including a second insulating film that covers the gate electrode, the drain electrode, and the first insulating film between the gate electrode and the drain electrode, wherein the second insulating film is made of silicon nitride (SiN) with a composition ratio of silicon against nitride (Si/N) that is smaller than the composition ratio of silicon against nitrogen (Si/N) of the first insulating film.
