Lateral Implanted RESURF GaN MOSFETs with BV up to 2.5 kV

Abstract

We report on the demonstration of enhancement- mode n-channel lateral implanted GaN high-voltage MOSFET with breakdown voltage up to 2.5 kV or specific on-resistance as low as 30 mOmegaldrcm2. With proper RESURF dose, drain current up to 0.1 A and breakdown voltage up to 1570 V is realized on the same device. The reliability lifetime defined by the failure criteria of DeltaIp/Ip=20% was determined to be over 11 years at 250degC.
