The lateral super junction (SJ) power devices suffer the substrate-assisted depletion (SAD) effect, which breaks the charge balance of SJ resulting in the low breakdown voltage (BV). A solution based on enhancin...
A new design concept is proposed to eliminate the substrate-assisted depletion effect that significantly degrades the breakdown voltage (BV) of conventional super junction-LDMOS. The key feature of the new concept i...
A new super junction LDMOST structure that suppresses the substrate-assisted depletion effect is designed with an n^+-floating layer embedded in the high-resistance p-type substrate by implanting phosphor or arsenic....

In this paper, we propose a novel low on-resistance Super Junction (S J) Lateral Double-diffusion MOSFET (LDMOST) which has split p column structures with rated voltage of 60-100V. The key feature of this new stru...
