Abstract:
1. A printed circuit board comprising: a core substrate comprising a resin substrate having an opening, the core substrate having an upper surface and a lower surface on an opposite side of the upper surface; a first capacitor formed in the opening of the resin substrate and having a first electrode structure having an upper portion facing to the upper surface of the core substrate and a second electrode structure having a lower portion facing to the lower surface of the core substrate; an upper insulating layer formed over the upper surface of the core substrate and having a conductive circuit formed over the upper insulating layer, the upper insulating layer having a via hole electrically connecting the upper portion of the first electrode structure of the first capacitor and the conductive circuit of the upper insulating layer; and a lower insulating layer formed over the lower surface of the core substrate and having a conductive circuit formed over the lower insulating layer, the lower insulating layer having a via hole electrically connecting the lower portion of the second electrode structure of the first capacitor and the conductive circuit of the lower insulating layer.
