A method is provided for establishing through substrate vias (TSVs) within a substrate. The method includes: forming at least one recess in a front-side of a wafer; filling, at least partially, the at least one recess with a sacrificial material from the front-side of the wafer; thinning the wafer from a back-side to reveal the at least one recess at least partially filled with the sacrificial material; removing from the back-side of the wafer the sacrificial material from the at least one recess; and filling the at least one recess from the back-side of the wafer with a conductive material to provide the at least one through substrate via. |
