Title:
COMPOSITE ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2016/021529
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the stress acting on a thin-film capacitor in a composite electronic component provided with the thin-film capacitor and a thin-film circuit element. This composite electronic component (1) is provided with: an insulating substrate (2) having a thin-film capacitor (3) formed on one main surface thereof; an insulating protective layer (4) stacked so as to cover the thin-film capacitor (3); first lead-out wiring (7a) which is formed on the insulating protective layer (4), and which is connected to the thin-film capacitor (3); a first resin-layer section (5a) stacked on the insulating protective layer (4); first and second thin-film resistors (9a, 9b) provided in the first resin-layer section (5a); a third through hole (6c) formed passing through the first resin-layer section (5a) in the thickness direction such that the first lead-out wiring (7a) can be seen therethrough; first rewiring (8a) which is formed on the first resin-layer section (5a), and which is connected to the first lead-out wiring (7a) through a second through hole (6c); and a second resin-layer section (5b) stacked on the first resin-layer section (5a). The inside of the third through hole (6c) is filled with the resin of the second resin-layer section (5b). The third through hole (6c) is formed in a position offset from the thin-film capacitor (3) in a planar view.
