초록

This paper show the measured result of electrical characteristics of SOI-LDMOSFET that is one of the high voltage devises. Especially, we observed changes of breakdown voltage, threshold voltage, on-resistance, drain current, and transconductance in accordance with drift length, main parameter of LDMOSFET. Also, we achieved reliability analysis about device operation in high temperature environment because LDMOS is applied to smart power IC.
