CONSTITUTION:Short-circuit regions are formed so as to constitute the bypasses of the interfaces presenting rectifying action, thereby lowering or eliminating the rectifying action in the bypasses. For instance, in the position corresponding to the position for the diffusion region of a high-concentration P-type impurity in a P-N junction diode, a plurality of high-concentration P-type impurity regions 5 are formed at a predetermined interval d, and short-circuit regions 6 by diffusion of a high-concentration N-type impurity are formed at the electrode 4 side between the regions 5 (of the places of interval d), thereby enabling an epitaxial growth layer 2 and the electrode 4 to be short-circuited in the short- circuit regions 6. In this structure, rectifying action is presented in the interfaces between the regions 5 and the layer 2, but the short-circuit regions 6 constituting the bypasses present no rectifying action. With this, the threshold voltage can be set to a desired value, and thus characteristics compatible with the use conditions can be designed.

Filed: 1989-06-29
Abstract: PURPOSE:To reduce dynamic current consumption by connecting a 2nd P-channel transistor(TR) between the source of a 1st P-channel TR and a power supply and a 2nd P-channel TR between the source of a 1st N-channel TR and ground respectively, and driving the MOS TRs with an input signal. CONSTITUTION:A 2nd P-channel MOS TR P2 is inserted between the source of a P-channel MOS TR P1 and a power supply 3 and a 2nd N-channel MOS TR N2 is inserted between a 1st N-channel MOS TR N2 and ground 4, respectively. The potential when the 4 MOS TRs are turned on while the input signal is inverted exists within a very small potential region between the potential sum of the threshold levels of the 2 N-channel MOS TRs and the power supply potential subtracted by the threshold levels of the 2 N-channel MOS TRs. Thus, since a time of many currents flow at the time of inverting the signal is very small, the dynamic current consumption is reduced.
