PECVD SiO2 Layers on AlGaN/GaN Mental Oxide Semiconductor Heterostructure Field-Effect Transistor
【摘要】 为了进一步减小栅漏电,提高击穿电压,将MOS结构的优点引入ALGaN/GaNHEMT器件中,研制并分析了新型的基于AlGaN/GaN的MOS-HFET结构。采用等离子增强气相化学沉积(PECVD)的方法生长了50nm的SiO2作为栅绝缘层,新型的AlGaN/GaNMOS-HFET器件栅长1μm,栅宽80μm,测得最大饱和输出电流为784mA/mm,最大跨导为44.25ms/mm,最高栅偏压+6V。
【Abstract】 With SiO2 layers as the insulating gate, AlGaN/GaN mental oxide semiconductor heterostructure field-effect transistor are demonstrated. Based on the plasma enhanced chemical vapor deposition (PECVD) method, high quality SiO2 enables the decrease of gate leakage current and a large gate swing voltage. With the gate length of 1 μm and the width 80 μm, MOS-HFET achieved transconductance 44 ms/mm and the maximum drain current 784mA/mm.
