Abstract
In a Static Induction Transistor Logic (or an Integrated Injection Logic) semiconductor device having a lateral PNP transistor used as an injector and a longitudinal field effect transistor (or a longitudinal NPN transistor) used as a driving transistor, a collector of a transistor for a level-converter which converts a signal level from an upper layer or first logic level to a lower layer or second logic level is connected to a gate (or a base) of a driving transistor placed in the lower layer through a current limiting element integrated on the same chip to effectively use an injection current in a signal-level converting circuit used in a Static Induction Transistor Logic or in an Integrated Injection Logic which is constructed by using a laminated circuit construction.
