Patent ID: 7808073

Claim:
A semiconductor device comprising: a base plate; a semiconductor element which is provided on the base plate, and which comprises: a semiconductor substrate including an integrated circuit on a top side thereof and connection pads connected to the integrated circuit, an insulation layer formed on the semiconductor substrate and having openings at least partly exposing the connection pads, a plurality of wirings formed on the insulation layer and having first portions electrically connected with the connection pads and second portions disposed on a top surface of the insulation layer, a plurality of columnar external connection electrodes formed on the second portions of the wirings, and a sealing film provided between the external connection electrodes; a plurality of passive elements which are provided on the base plate and each of which comprises: a semiconductor substrate, a thin-film passive element having end portions and formed on the semiconductor substrate, an insulation layer formed on the thin-film passive element and the semiconductor substrate and having openings exposing the end portions of the thin-film passive element, a plurality of wirings formed on the insulation layer and having first portions electrically connected with the end portions of the thin-film passive element and second portions disposed on a top surface of the insulation layer, a plurality of columnar external connection electrodes formed on the second portions of the wirings, and a sealing film provided between the external connection electrodes; an insulating layer provided on the base plate around the semiconductor element and the passive elements, and between the semiconductor element and one of the passive elements adjacent to the semiconductor element; an insulating film which covers the semiconductor element, the passive elements, and the insulating layer; a plurality of upper wirings formed on the insulating film, the upper wirings comprising a first upper wiring which electrically connects at least one of the external connection electrodes of the semiconductor element and one of the external connection electrodes of the passive element nearest to the semiconductor element among the passive elements, a second upper wiring which is electrically connected to one of the columnar external connection electrodes of the semiconductor element, and a third upper wiring which is electrically connected to one of the columnar external connection electrodes of one of the passive elements; and a plurality of solder balls comprising a first solder ball which is electrically connected to the one of the columnar external connection electrodes of the semiconductor element and a second solder ball which is electrically connected to one of the columnar external connection electrodes of one of the passive elements.
