Abstract
A semiconductor integrated circuit includes a high-potential-side circuit region, a high-voltage junction termination structure surrounding the high-potential-side circuit region, and a low-potential-side circuit region surrounding the high-potential-side circuit region via the high-voltage junction termination structure which are integrated into a single chip, and wherein a first distance between a looped well region and a buried layer in a region in which a first contact region is formed is smaller than a second distance between the looped well region and the buried layer in a region in which a carrier reception region is formed.
