Abstract: A method for forming a package structure may comprise applying a die and vias on a carrier having an adhesive layer and forming a molded substrate over the carrier and around the vias, and the ends of the vias and mounts on the die exposed. The vias may be in via chips with one or more dielectric layers separating the vias. The via chips 104 may be formed separately from the carrier. The dielectric layer of the via chips may separate the vias from, and comprise a material different than, the molded substrate. An RDL having RDL contact pads and conductive lines may be formed on the molded substrate.
