Abstract

SiC lateral power semiconductor device has high breakdown voltage and low on-state voltage drop due to the material characteristics. And, because the high breakdown voltage can be obtained, RESURF technique is mostly used in silicon power semiconductor devices. In this paper, we presents the electrical characteristics of the 4H-SiC RESURF LDMOSFET as a function of the epi-layer length, concentration and thickness. 240~780V of breakdown voltage can be obtained as a function of epi-layer length and thickness with same epi-layer concentration.
