Patent ID: 7968800

Claim:
A passive component incorporating interposer comprising: a resin substrate having wiring layers on both surfaces; one or more passive components mounted on the wiring layer on one surface of the resin substrate; a first insulating layer made of woven fabric or non-woven fabric and thermosetting resin laminated on the other surface of the resin substrate not mounted with the passive component; a second insulating layer made of woven fabric or non-woven fabric and thermosetting resin laminated on the surface of the resin substrate mounted with the passive component and formed with a space larger than an outside dimension of the passive component; a first wiring layer formed on a surface of the first insulating layer not contacting the resin substrate; a second wiring layer formed on a surface of the second insulating layer not contacting the resin substrate; and a through hole for electrically connecting the wiring layers disposed on both sides of the resin substrate, the first wiring layer, and the second wiring layer; wherein the first wiring layer is formed to enable mounting of a semiconductor element.
