A semiconductor device includes a semiconductor layer, a first electrode located over the semiconductor layer and connected to the semiconductor layer, a second electrode spaced from the first electrode and located over the semiconductor layer and connected to the semiconductor layer, an insulation film located over the semiconductor layer, and a third electrode interposed between the first electrode and the second electrode, and location over a portion of the insulation film. The insulation film includes a first layer located on the semiconductor layer and between the first electrode and the second electrode and comprising silicon nitride, and a second layer located on the first layer and between the first electrode and the third electrode as well as between the second electrode and the third electrode, and comprising silicon nitride and an amount of oxygen larger than the first layer. |
