Abstract

PURPOSE:To prevent a leakage current from taking place when the thickness of an epitaxial layer is reduced, by providing gate-operating regions on the bottoms of static induction transistor drain regions of a static induction transistor logic circuit. CONSTITUTION:An injector-operating P-type region 23 of a lateral bipolar PNP transistor and gate-operating P-type regions 24 of an inverse static induction transistor are selectively produced in an N<->-type epitaxial layer 22 provided on an N<+>- type semiconductor substrate 21. Drain regions 25, 26 and P<->-type regions 27 are then produced so that the P<->-type regions are located in contact with the bottoms of the drain regions, have the same width as the drain regions and are connected to the P-type regions. As a result, the channel width of the static induction transistor is substantially reduced by the P<->-type regions 27. Even if an impurity diffuses out of the N<+>-type substrate into the N<->-type epitaxial layer, a leakage current is prevented from taking place between the source and drain. Therefore, the thickness of the epitaxial layer can be reduced.
