Design curves of breakdown voltage at field plate edge and effect of interface charge
Useful design curves of breakdown voltage are provided, which allow determination of breakdown voltage at the field plate edge in terms of field plate length, oxide thickness, and substrate doping concentration. The effect of the interface charge on the breakdown voltage is analyzed and determined also from the curves. The analytical results show a fair agreement with the two-dimensional device simulations using MEDICI as well as with the experimental results reported.
