ABSTRACT:
A trench MOSFET device with embedded Schottky rectifier, Gate-Drain and Gate-Source diodes on single chip is formed to achieve device shrinkage and performance improvement. The present semiconductor devices achieve low Vf and reverse leakage current for embedded Schottky rectifier, have overvoltage protection for GS clamp diodes and avalanche protection for GD clamp diodes.
