Abstract :
A lateral trench power MOSFET in the 250 V class, with a reduced specific on-resistance is proposed. Simulation results of an optimized device structure exhibits a low specific on-resistance of 7 mOmega -cm2, which is 2.5times lower than that of the conventional lateral DMOSFET. Effects of design parameters on the device performance are examined. An improved device structure with reduced sensitivity to process variations is also presented.
