ABSTRACT:
In an integrated semiconductor device of the IIL type which includes a switching transistor and an injector transistor for supplying carriers to drive the switching transistor, the switching transistor is a static induction transistor which comprises: cylindrical current channels for providing current paths between a source and drains; a control gate surrounding the outer boundaries of the channels to form pn junctions therebetween and being injected with carriers from the injector transistor to control the current flow in the channels; and floating gates disposed inside the respective channels to form pn junctions therebetween. The floating gates are electrically floating and have a potential affected by the potential of the control gate to contribute to the channel conduction controlling action together with the control gate.
