An efficient and low cost approach for depositing uniform silicon dioxide layers on GaN by liquid phase deposition (LPD) that is near room temperature will be described. The self-align and self-passivation process of LPD can ease the device fabrication. AlGaN/GaN metal oxide semiconductor heterostructure field effect transistors (MOSHFETs) with liquid phase deposited SiO2 as the insulating gate are demonstrated. Comparison between the AlGaN/GaN MOSHFETs and heterostructure field effect transistors (HFETs) will be made. Lower leakage currents, larger gate swing voltages and flatter transconductance ranges can be seen in MOSHFETs.
