摘要:
A plurality of wirings, column-shaped electrodes, sealing films, and soldering balls, are provided on a third upper-layer insulating film formed on a silicon substrate. A spirally configured thin-film inductive element is disposed beneath the bottom surface of a ground insulating film formed beneath the silicon substrate. The inner and outer end portions of the thin-film inductive element are respectively connected to the wirings via a vertical conductor disposed in the silicon substrate. In this case, it is not required to secure a certain area otherwise needed for the formation of the thin-film inductive element over the surface of the third upper-layer insulating film that accommodates the wirings. Hence, even when the thin-film inductive element has been provided, it is possible to evade a feasibility to incur restraint on the distribution of the wirings formed over the surface of the third upper-layer insulating film.
