Abstract
A semiconductor device package includes a carrier substrate molded of a non-laminate material. A plurality of conductive metal balls are molded within the non-laminate carrier substrate to provide an electrical connection between opposite sides of the substrate. The conductive metal balls provide conductive columns through the substrate for electrically connecting a chip mounted on one side of the substrate to solder balls on an opposite side of the substrate for mounting the package on a printed circuit board. The conductive columns eliminate the need for via holes which are used in known packages. The package with conductive columns provides a more compact, more precise, and lower cost package which is less susceptible to moisture damage than the known packages employing via holes.
