Abstract
An 80V class integrable lateral trench power MOSFET based on a shallow trench (~1.0μm) structure with a low Figure of Merit (R on ×Q g ) for high frequency switching applications is presented. A simulated optimized MOSFET exhibits a Figure of Merit of 240 mOhm-nC, which is over 2.5X improvement on the best reported lateral trench power MOSFETs in the same voltage class. Prototype devices from the first silicon run exhibit a threshold voltage of 1V, specific on-resistance of 3.05 mOhm-cm 2 , breakdown voltage of 55V and Figure of Merit of 645 mOhm-nC at a gate bias of 10V.
