A through-wafer via interconnect region is in a circuit portion of a wafer, the circuit portion including at least one electrically conducting metal layer and configured for use, after dicing of the wafer, as one of a plurality of layers stacked vertically to form a three dimensional integrated circuit. Within the metal layer in the circuit portion, the metal is removeably distributed such that the ratio of metal to nonmetal area, within the via region, varies by less than a predetermined amount from the ratio of metal to nonmetal area outside the via region.
