چکیده
Abstract In this paper, a novel super-junction (SJ) MOSFET with enhanced switching performance and ruggedness is proposed investigated by the method of TCAD simulations. An N + /P - polysilicon junction gate electrode separation layer between P-base P-pillar are introduced to trench SJ-MOSFET. For gate, P located in bottom plays role insulating layer, which efficiently reduces charge (Q G ), thus increasing speed reducing loss. The does not contact so depletion region formed drain GD ) reduced. Besides, specific also inhibits activation parasitic bipolar transistor (BJT) improve unclamped inductive (UIS) capability. results simulation reveal that SJ-MOSFET better ruggedness.

Low Voltage Super Junction MOSFET Simulation and Experimentation
The application of Super Junction concepts to a low voltage power MOSFET is investigated. The body junction is modified with the addition of a high energy implant, resulting in an increased breakdown voltage. Simulations are used to quantify the relationship between dose and breakdown voltage, resulting in a predicted 35% Rds(on) reduction. This is confirmed through experiment, and a 19% reduct...
متن کاملDriving and Layout Design for Fast Switching Super-Junction MOSFETs
Power MOSFET technology has been developed towards higher cell density for lower on-resistance. There are, however, silicon limits for significant reduction in the onresistance with the conventional planar MOSFET technology because of its exponential increase in onresistance according to the increase of blocking capability. One of efforts to overcome the silicon limit is superjunction technolog...
