Abstract:
An inverting gate voltage channel induced semiconductor device with operating characteristics similar to multiple device Complementary Metal Oxide Semiconductor (CMOS) systems, said inverting gate voltage channel induced semiconductor device being formed in a semiconductor substrate characterized by a selection from the group consisting of:said semiconductor substrate contains both N and P-type metallurgical dopants essentially homogeneously distributed therein at substantially equal doping levels; and said semiconductor substrate contains both N and P-type metallurgical dopants essentially homogeneously distributed therein at substantially different doping levels; said inverting gate voltage channel induced semiconductor device comprising two junctions, termed source and drain, which are separated by a first semiconductor channel region, and further comprising two additional junctions, termed source and drain, which are separated by a second semiconductor channel region, wherein gates, to which semiconductor channel region field induced effective doping effecting voltage can be applied, are associated with each of the first and second semiconductor channel regions, said gates being offset from said first and second semiconductor channel regions by insulating material; such that during use application a sufficient positive voltage to said gates will attract electrons to said first and second semiconductor channel regions, and such that application of sufficient negative voltage to said gates will attract holes to said first and second semiconductor channel regions, the purpose of applying such gate voltage being to affect field induced effective doping type of said first and second semiconductor channel regions between respective source and drain junctions, which source junctions are each essentially non-rectifying, and which drain junctions are rectifying junctions; in which inverting gate voltage channel induced semiconductor device the rectifying drain junction associated with said first semiconductor channel region is electrically interconnected with the rectifying drain junction associated with said second semiconductor channel region, and in which said gates associated with said first and second channel regions are electrically interconnected; such that during operation the electrically noninterconnected essentially non-rectifying source junctions are held at different voltages, and application of a gate voltage affects semiconductor channel region effective doping type in both said first and second channel regions by field induced means, and thus which electrically interconnected rectifying drain junction forward conducts as a result of semiconductor type metallurgically present or field induced by said applied gate voltage, thereby controlling the voltage present at the electrically interconnected rectifying drain junctions essentially through said forward conducting rectifying drain junction; the basis of operation of said inverting gate voltage channel induced semiconductor device being that said rectifying drain junctions associated with said first and second semiconductor channel regions thereof are comprised of at least one material that forms a rectifying junction to each of said first and second semiconductor channel regions when it is either N or P-type by either metallurgical or field induced means.
