Abstract:
A printed circuit board having embedded capacitors includes 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; dielectric layers formed by depositing alumina films on the first circuit layers by atomic layer deposition; second circuit layers formed on the dielectric layers and 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. The manufacturing method of the printed circuit board is also disclosed.
