Abstract
There is provided a semiconductor device able to prevent performance degradation of an inductor element provided thereon. A high resistance region is provided below the inductor element formed on the semiconductor substrate. The high resistance region is formed deeper than the well regions of the p-channel and n-channel MOS transistors, thus preventing induction of an eddy current by the magnetic flux generated from the inductor element.
