Abstract:
To suppress the noise caused by an inductor leaks to the outside, and also to be configured such that magnetic field intensity change reaches the inductor.An inductor surrounds an internal circuit in a planar view and also is coupled electrically to the internal circuit. The upper side of the inductor is covered by an upper shield part and the lower side of the inductor is covered by a lower shield part. The upper shield part is formed by the use of a multilayered wiring layer. The upper shield part has plural first openings. The first opening overlaps the inductor in the planar view.
