Abstract

A first spiral inductor is provided on the semiconductor substrate. A dielectric film covers the first spiral inductor. A second spiral inductor is provided on the dielectric film. A connecting portion penetrates the dielectric film and electrically connects a first inner end portion of the first spiral inductor to a second inner end portion of the second spiral inductor. Winding direction of the first spiral inductor from a first outer end portion toward the first inner end portion is the same as the winding direction of the second spiral inductor from a second inner end portion toward the second outer end portion. A wire of the second spiral inductor is disposed opposite the first spiral inductor with the dielectric film between them. The wire of the second spiral inductor is disposed in gaps between windings of the first spiral inductor, when viewed in a plan view.
