MOS-GATED POWER DEVICES, METHODS, AND INTEGRATED CIRCUITS

摘要

MOS-gated devices, related methods, and systems for vertical power and RF devices including an insulated trench and a gate electrode. A body region is positioned so that a voltage bias on the gate electrode will cause an inversion layer in the body region. Permanent electrostatic charges are included in said insulation material. A conductive shield layer is positioned above the insulated trench, to reduce parasitic capacitances.
