A Breakdown Voltage Model of a PSOI Structure with a p-Type Buried Layer
-
Abstract
A new PSOI structure with a p-type buried layer is developed,which is called BPSOI.Its mechanism of breakdown is an additive electric field modulation,which inducts new electric field peaks in surface electric field distribution by p-type buried layer charges.The on-resistance is decreased as a result of increasing drift region doping which is due to the neutralism of the p-type buried layer.The result is that the breakdown voltage is increased by 52%～58% and the on-resistance is decreased by 45%～48% in virtue of the 2D MEDICI simulation.-
