A wafer level integration module and method for fabricating are disclosed according to a construction whereby semiconductor functional device fabrication is carried out only after interconnect structures are processed on a bare wafer. The fabrication and processing include forming interconnect structures in a first side of a wafer. An insulation layer is deposited on the first side of the wafer. A conductive layer is deposited on the insulation layer so as to fill the interconnect structures and contact the insulation layer on the walls thereof. The conductive layer on the interconnect structures forms interconnection contacts on the first side of the wafer and interconnection vias extending into the wafer. The conductive layer including the interconnection contacts is exposed on the first side of the wafer. A semiconductor functional device is fabricated on the first side of the wafer and interconnected with the interconnection contacts during the fabricating. Portions of the first conductive layer associated with the interconnection vias are exposed from the second side of the wafer. A portion of the first conductive layer can be selectively removed to form interconnection via redistribution connection structures that can be filled with a low resistivity material to form low resistivity redistribution interconnect with the semiconductor functional device through the first conductive layer. |
