Abstract

Various embodiments of the present disclosure are directed towards an integrated circuit (IC) including a first through substrate via (TSV) within a first semiconductor substrate. The first semiconductor substrate has a front-side surface and a back-side surface respectively on opposite sides of the first semiconductor substrate. The first semiconductor substrate includes a first doped channel region extending from the front-side surface to the back-side surface. The first through substrate via (TSV) is defined at least by the first doped channel region. A first interconnect structure on the front-side surface of the first semiconductor substrate. The first interconnect structure includes a plurality of first conductive wires and a plurality of first conductive vias, and the first conductive wires and the first conductive vias define a conductive path to the first TSV.
