Abstract

A semiconductor package includes a first semiconductor chip mounted on a substrate and a second semiconductor chip mounted on top of the first semiconductor chip. The first chip includes a plurality of metal lines which may be deposited at its top surface, and the metal lines are isolated from circuitry in the first chip. Wire bonds connect pads on the second chip to metal lines on the first chip. Additional wired bonds connect the metal lines on the first chip to terminals on the substrate. Conductive through-silicon vias or solder bumps may replace the wire bonds, and additional chips may be included in the package.
