Abstract:
1. A printed circuit board comprising: a conductor portion; an insulating resin layer formed over the conductor portion; a thin-film capacitor formed over the insulating resin layer and comprising a first electrode, a second electrode and a high-dielectric layer interposed between the first electrode and the second electrode; and a via-hole conductor structure formed through the second electrode and insulating layer and electrically connecting the second electrode and the conductor portion, the via-hole conductor structure having a first portion in the second electrode and a second portion in the insulating layer, the first portion of the via-hole conductor structure having a truncated-cone shape tapering toward the conductor portion along a first direction extending through the second electrode, and the second portion of the via-hole conductor structure extending through the insulating layer along a second direction different from the first direction such that the first portion and second portion of the via-hole conductor structure form an angle at a juncture of the first portion and the second portion.
