STATIC INDUCTION TRANSISTOR AND INTEGRATED CIRCUIT DEVICE USING SAME

摘要

A static induction transistor (SIT) has a channel region thereof with a length-to-width ratio L/W of at least about 0.5. Sucha 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 collector/gate region. This SIT is simple in structure, which enables a marked increase in the integration density.
