Abstract
A semiconductor device which includes a channel region of predetermined conductivity type having a pair of opposing surfaces (11 or 33) , a control element of opposite conductivity type disposed on one of the opposing surfaces (13 or 31) and a pair of spaced apart electrodes (17, 19 or 35, 37) disposed over the other of the opposing surfaces. The control element and channel region form a pn junction therebetween. An electrically insulating layer (15) can be disposed between the spaced apart electrodes (17, 19) and the channel region (11) in a high frequency embodiment.
