SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

The purpose of the present invention is to improve semiconductor integrated circuit reliability. A semiconductor integrated circuit (40) comprises: a first conduction-type first well region (2); a second conduction-type second well region (3) provided in an upper section of the first well region (2); and a first conduction-type current suppression layer (21) provided at a distance from the first well region (2), in a lower section of a second conduction-type semiconductor substrate 1 directly below the first well region (2).
