Abstract
A semiconductor integrated circuit is supplied with a power source voltage to a circuit element forming layer thereof from a conductive layer through a substrate and a certain region made of a semiconductor type identical to that of the substrate. The conductive layer is formed on a back surface of the substrate, and the certain region makes contact with a front surface of the substrate. The circuit element forming layer is provided on the front surface side of the substrate and connects to the certain region. Alternatively, a region may be provided to extend from the circuit element forming layer to the substrate so as to provide a conductive path for supplying the power source voltage from the back surface of the substrate.
