Patent ID: 7888599

Claim:
A method of fabricating a printed circuit board including an embedded capacitor, comprising the steps of: (A) forming an opening through a copper clad laminate so that the opening is formed through upper and lower copper foil layers of the copper clad laminate and has a predetermined length; (B) forming first copper layers on the upper and lower copper foil layers of the copper clad laminate and on walls of the opening; (C) packing a high dielectric material in the opening, on the walls of which the first copper plating layers have already been formed; (D) forming second copper plating layers on the first copper plating and on the high dielectric material; and (E) partially etching the upper and lower copper foil layers, and the first and second copper plating layers in such a way that first and second electrodes are formed so as to extend along both longitudinal walls of a structure, which consists of the high dielectric material, to be in contact with the structure.
