Abstract:
A package for mounting a semiconductor device to a circuit board, comprising:a substrate with a top surface and a bottom surface, the substrate having a plurality of electrically conductive vias extending from the top surface of the substrate to the bottom surface of the substrate;a semiconductor device having an active surface, the active surface having a plurality of bonding pads;an adhesive with a top surface and a bottom surface, the adhesive having a plurality of holes extending from the top surface of the adhesive to the bottom surface of the adhesive, the adhesive disposed between the substrate and the semiconductor device such that the plurality of holes in the adhesive are at least partially aligned with the plurality of vias in the substrate and at least partially aligned with the plurality of bonding pads on the active surface of the semiconductor device;a plurality of external electrical contacts proximate to the bottom surface of the substrate, each of the plurality of external electrical contacts being electrically coupled to a corresponding one of the plurality of vias; andwhereineach of the plurality of bonding pads is electrically coupled to a corresponding one of the plurality of vias.
