Patent ID: 8351215

Claim:
A manufacturing method of a chip embedded printed circuit board comprising: forming an insulating film on a metal foil; mounting a chip having terminals on which posts are formed at an upper part over the insulating film, wherein forming the insulating film on the metal foil is performed before mounting the chip provided with the posts at the upper part over the metal foil; forming an insulating layer over the insulating film and the chip, top surfaces of the posts and all top surfaces of the insulating layer being on a same horizontal plane; forming via holes to expose a portion of a top surface of the metal foil by removing a portion of the insulating layer and the insulating film; forming vias by filling the via hole with conductive material; forming upper patterns connected to the posts and the vias on the insulating layer; and forming lower patterns connected to the vias by removing a portion of the metal foil, wherein all of the via holes formed in forming the via holes are located on an area except for a vertical upper area of the chip, and the posts are made of any one of copper aluminum and solder.
