We have proposed and fabricated an AlGaN/GaN high-electron-mobility transistor (HEMT) with an additional gate, which exhibits a low leakage current and a high breakdown voltage for high-voltage switching applications. The additional gate between the main gate and the drain is specially designed to decrease the electric field concentration at the drain side of the main gate. The leakage current of the proposed HEMT is decreased considerably and the breakdown voltage increases without sacrificing the transconductance and the drain current. The experimental results show that the off-state breakdown voltage and the leakage current of the proposed HEMT are 362 V and 75 nA while those of the conventional HEMT are 196 V and 428 nA, respectively.
