Abstract :
2D MEDICI simulator is used to investigate hardening solutions to single-event burnout (SEE). SEE parametric dependencies such as carrier lifetime reduction, base enlargement, and emitter doping decrease have been verified and a p+ plug modification approach for SEE hardening of power MOSFETs is validated with simulations on actual device structures
