Abstract
A method is described. The method includes creating a partial through-substrate via (TSV) plug in a front side of a wafer, the partial TSV having a front side and a back side. The back side of the partial TSV extending toward a front side of a substrate but not into a bulk of the substrate. A cavity is etched in a back side of the wafer that exposes the partial TSV plug. An insulator is applied to the etched back side of the wafer. A portion of the partial TSV plug is exposed by removing a portion of the insulator. A conductive material is deposited to connect the exposed, partial TSV plug to a surface on the back side of the wafer.
