PROBLEM TO BE SOLVED: To prevent the malfunction of a logical circuit by reducing a fluctuation in a power source voltage. SOLUTION: The channels 7p and 7n of a p-type transistor Mp and an n-type transistor Mn are formed by tapering in a CMOS inverter shown in a figure. A p-type diffusion layer 5p and an n-type diffusion layer 5n to be connected to a power source and the ground are formed with a larger width. A p-type diffusion layer 6p and an n-type diffusion layer 6n to be connected to output wiring are formed with a smaller width. COPYRIGHT: (C)2007,JPO&INPIT
