Patent ID: 8826531

Claim:
A method for manufacturing a substrate for a semiconductor package, comprising: laminating a thin-film dielectric layer to a dielectric layer having a plated, etched or printed circuit first conductive pattern on at least one side to produce a laminated assembly comprising: providing the dielectric layer with the first conductive pattern on the at least one side of the dielectric layer; and applying an adhesive layer simultaneously to both the at least one side of the dielectric layer and the first conductive pattern, the adhesive layer being on an inside surface of the thin-film dielectric layer opposing an outside surface of the thin-film dielectric layer, wherein the adhesive layer forms part of the thin-film dielectric layer; laser-drilling a plurality of perforations on the outside surface of the thin-film dielectric layer, wherein the perforations comprise: conductor channels from the outside surface of the thin-film dielectric layer to contact the adhesive layer, wherein the adhesive layer remains between the conductor channels and the first conductive pattern; and blind via holes formed from the outside surface of the thin-film dielectric layer through the thin-film dielectric layer and the adhesive layer to contact the first conductive pattern; and depositing metal within the perforations to form electrical contact to the first conductive pattern.
