Abstract
A vertical IGFET comprising a substantially planar silicon wafer with a source electrode on one major surface and a drain electrode on the opposite major surface is disclosed. An insulated gate electrode, which includes a conductive finger portion surrounded by an insulating layer, is internally disposed in the silicon wafer such that a predetermined voltage applied to the gate electrode will regulate a current flow between the source and drain electrodes. The device is fabricated utilizing an epitaxial lateral overgrowth technique for depositing monocrystalline silicon over the insulated gate which is disposed on a silicon substrate.
