| abstract |
An apparatus and method are provided for integrating TSVs into devices prior to device contacts processing. The apparatus includes a semiconducting layer; one or more CMOS devices mounted on a top surface of the semiconducting layer; one or more TSVs integrated into the semiconducting layer of the device wafer; at least one metal layer applied over the TSVs; and one or more bond pads mounted onto a top layer of the at least one metal layer, wherein the at least one metal layer is arranged to enable placement of the one or more bond pads at a specified location for bonding to a second device wafer. The method includes obtaining a wafer of semiconducting material, performing front end of line processing on the wafer; providing one or more TSVs in the wafer; performing middle of line processing on the wafer; and performing back end of line processing on the wafer. |
