Popis: In this paper, a novel trench shielded 600V MOSFET with buried field ring is proposed and demonstrated. The proposed structure achieves an active area die shrink of 35-55% compared to a conventional 600V planar MOSFET. Furthermore, it almost doubles the Unclamped Inductive Switching (UIS) rated current and improves 0.3% of the efficiency compared to the Superjunction device. It also shows better diode reverse recovery performance than Superjunction device.
