Abstract:
A method for manufacturing a printed circuit board includes forming an opening portion in a substrate, positioning chip capacitors in the opening portion of the substrate such that the chip capacitors are accommodated in the opening portion of the substrate, forming a buildup structure including an interlayer resin insulating layer and a conductive layer over a surface of the substrate and the chip capacitors accommodated in the opening portion of the substrate, and forming on a surface of the buildup structure bump structures positioned to mount an IC chip such that the chip capacitors in the opening portion of the substrate are positioned directly below the IC chip.
