Abstract
A printed circuit board includes a first insulating layer with a through-hole and a capacitor disposed along a side surface of the through-hole. The capacitor has first and second electrode layers arranged with a dielectric layer between them. A first interconnection layer is positioned on an upper side of the through-hole and includes first and second metal layers respectively contacting the first and second electrode layers. Portions of the first and second metal layers are removed to form cut-out regions that facilitate electrical routing while maintaining the layered capacitor structure within the through-hole.
