Abstract

A method for manufacturing a capacitor embedded in a PCB includes: preparing a copper clad lamination (CCL) substrate having a reinforcement member and copper foils formed on both surfaces of the reinforcement member; planarizing surfaces of the copper foils of the CCL substrate; forming a dielectric layer on the planarized surface of the copper foils; and forming a top electrode on the dielectric layer.
