Static induction transistor and integrated circuit device using same

摘要

A static induction transistor (SIT) which is made to operate with a forward gate bias by maintaining the width of the channel region at an appropriate value. Such an improved SIT is used as the inverter transistor in a merged transistor logic (MTL) semiconductor IC (integrated circuit) to reduce the time delay-power product by an order or more. The collector region of a bipolar load transistor is continuous to or also serves as the gate region of the inverter SIT. A plurality of channel regions are formed penetrating through this collection/gate region. This SIT is simple in structure, which enables a marked increase in the integration density.
