Abstract :
A normally-off recess-gated GaN/AlGaN MOSFET which applicable at green-energy system and automobile SoC technology has been demonstrated. By recess-gated process, the transistor is operated as a normally-off device which has advantages for less power loss, and easy circuit design. After the GaN/AlGaN MOSFET device design, the DC and RF characteristics are extracted and analyzed by TCAD simulation process. The Ion of 250 mA/mm, SS of 200 mV/dec, VB of 60 V, fT of 2 GHz, and fmax of 2.5 GHz are obtained.
