Abstract(in English) | AlGaN/GaN MOS HFETs with gate oxides formed by direct thermal oxidation of AlGaN/GaN epi layers have been developed for the first time. The fabricated MOS HFETs have exhibited high breakdown voltages, low gate leakage currents and stable operation at high drain voltages. Although MOS HFET with an undoped channel structure showed a reduced maximum drain current of 4OOmA/mm, higher drain currents up to 9OOmA/mm has been obtained by adopting a doped-channel structure. The gate leakage current has markedly decreased with the increase of the gate-oxide thickness, clearly showing the effectiveness of MOS structures in reducing gate leakage currents. The stable device operations at high drain voltages indicate that the trap density at the interface between the thermal oxide and epi layers will be low and the thermal oxide can be also used as a passivation film. |
