Semiconductor integrated circuit

摘要

Well regions of p-type are disposed in a surface region of an n-type Si substrate of a semiconductor integrated circuit. The p-type well regions are arranged in the shape of islands, and various semiconductor elements are formed in the p-type well islands. The substrate surface region between the p-type well islands is filled with a depletion layer, and an interconnection layer is disposed on an insulating film over that body region contained within the depletion layer.
