Abstract

Lateral FET structure is disclosed for bidirectional power switching, including AC application. A notch extends downwardly from a top major surface to separate left and right source regions and left and right channel regions, and direct the drift region current path between the channels around the bottom of the notch. Gate electrode means in the notch proximate the channels controls bidirectional conduction.
