Abstract
A semiconductor integrated circuit includes a semiconductor layer of a first conductivity type which is stacked on a support substrate with an insulating layer interposed between the semiconductor layer and the support substrate, a first well region of a second conductivity type buried in an upper part of the semiconductor layer so as to be separated from the insulating layer, a second well region of the first conductivity type buried in an upper part of the first well region, and an isolation region of the first conductivity type buried in the upper part of the semiconductor layer such that the isolation region surrounds the first well region and is separated from the first well region and the insulating layer.
