Patent ID: 8022311

Claim:
A method of manufacturing a printed circuit board having embedded capacitors, comprising: preparing a metal sheet, one surface of which includes a first circuit layer having a lower electrode and a circuit pattern formed in one circuit layer through an additive process; preparing a printed circuit board having a resin insulating layer formed thereon; laminating the metal sheet having the first circuit layer on the resin insulating layer of the printed circuit board to dispose the first circuit layer as an inner layer; removing the metal sheet to a thickness direction, thus exposing the first circuit layer and the resin insulating layer to the outside; laminating a single-sided dielectric sheet, including a dielectric layer and a metal layer for a second circuit layer formed on one surface of the dielectric layer, on the exposed first circuit layer and resin insulating layer to dispose the metal layer as an outer layer; patterning the metal layer for a second circuit layer, thus forming a second circuit layer including an upper electrode and a circuit pattern; forming a via hole for electrically connecting an interlayer circuit including the upper electrode and the lower electrode; and forming an outer circuit layer through a build-up process.
