Patent ID: 8642898

Claim:
A circuit board structure with capacitors embedded therein, comprising: a first core layer comprising a dielectric layer having two opposite surfaces, circuit layers disposed on the outsides of the two opposite surfaces of the dielectric layer, and at least two capacitors embedded respectively on the insides of the two opposite surfaces of the dielectric layer and individually electrically connecting with the circuit layer at the same side; and a second core layer and a third core layer disposed respectively on the two sides of the first core layer to form a core structure, wherein the second and third core layers individually comprise a dielectric layer having an outer surface and an inner surface opposite to the outer surface, a circuit layer disposed on the outer surface of the dielectric layer, at least one capacitor embedded on the inside of the outer surface of the dielectric layer and electrically connecting with the circuit layer, wherein the inner surfaces of the dielectric layers of the second and third core layers are respectively laminated with the two surfaces of the first core layer, and wherein the second and third core layers have no capacitors and circuit layers within their respective dielectric layers substantially near an interface with the first core layer.
