A semiconductor integrated circuit comprises logic cones having a structure in which substrates thereof are isolated from each other and substrate potentials can be controlled, and a potential switching section for supplying a substrate voltage from any of a first substrate bias supply potential and a second substrate bias supply potential to the logic cone. A signal output by a logic cone previous to a logic cone whose substrate potential is controlled is input as a trigger signal to the substrate supply potential switching section.
