Abstract:
1. A printed circuit board having embedded capacitors therein, comprising: a double-sided copper-clad laminate including first circuit layers formed in the outer layers thereof, the first circuit layers including bottom electrodes and circuit patterns; alumina dielectric layers formed on the first circuit layers through atomic layer deposition; second circuit layers formed on the dielectric layers, the second circuit layers including top electrodes and circuit patterns; one-sided copper-clad laminates formed on the second circuit layers; blind via-holes and through-holes formed in predetermined portions of the one-sided copper-clad laminates; and plating layers formed in the blind via-holes and the through-holes, wherein the second circuit layers include metal oxide seed layers of indium tin oxide (ITO) or ruthenium oxide (RuO
