Abstract
A vertical MOSFET includes source and gate electrodes on a major semiconductor surface, and a drain electrode on an opposing semiconductor surface. A shield electrode is disposed in proximity to the gate electrode so as to minimize feedback capacitance between the gate electrode and drain region. Additionally, the shield electrode increases the level of space charge limited current that can be supported in the drain region, and minimizes current crowding in the device.
