E-mode AlGaN/GaN HEMTs are generally promising candidate for switching power transistors due to their high breakdown voltage, high current density and low on-resistance. The threshold voltage (Vth) of normally-off mode AlGaN/GaN HEMTs with a self-aligned p-type GaN gate can be successfully improved by inserting a SiN insulator between the p-GaN and a Schottky gate electrode. The Vth can be increased from +1.5 V to +6.8 V by inserting of 15 nm SiN layer. Moreover, the sub-threshold drain and on-state gate currents of p-gate GaN transistor were decreased.
