An enhancement-mode GaN MOSFET with a low leakage current and an improved reliability is formed by utilizing a SiO2/Si3N4 gate insulation layer on an AlGaN (or InAlGaN) barrier layer. The Si3N4 portion of the SiO2/Si3N4 gate insulation layer significantly reduces the formation of interface states at the junction between the gate insulation layer and the barrier layer, while the SiO2 portion of the SiO2/Si3N4 gate insulation layer significantly reduces the leakage current. |
