Abstract
Lateral FET structure is disclosed for bidirectional power switching, including AC application. A plurality of integrated FETs each have left and right source regions and left and right channel regions with a common drift region therebetween, and conduct current in either direction according to the polarity of main terminals. Gating means includes gate electrode means disposed proximate and insulated from the channel regions and adapted for storing trapped charge tunneled through an insulated layer from a charging electrode.
