Patent ID: 7995352

Claim:
A printed circuit board comprising: a core substrate having a top surface and a bottom surface opposing the top surface; a build-up circuit layer provided on said core substrate, the build-up circuit layer comprising: a resin insulating layer, a conductor layer formed on the resin insulating layer, and a plurality of via hole structures provided in the resin insulating layer and electrically connected to said conductor layer, each via hole structure having a copper surface; and a capacitor provided between the top and bottom surfaces of the core substrate such that the capacitor is embedded within the printed circuit board, the capacitor comprising: a dielectric body having a plurality of first conductive films and a plurality of second conductive films embedded within a dielectric material, a first electrode formed on the dielectric body and electrically connected to the plurality of first conductive films, wherein a surface of the first electrode comprises copper and is physically connected to the copper surface of one of said plurality of via hole structures; and a second electrode formed on the dielectric body such that the dielectric body is provided between the first and second electrodes, the second electrode being electrically connected to the plurality of second conductive films, wherein a surface of the second electrode comprises copper and is physically connected to the copper surface of an other one of said plurality of via hole structures such that the first and second electrodes of the capacitor are physically connected to respective ones of said plurality of via hole structures.
