Abstract:
The present disclosure generally provides for integrated circuit (IC) structures with through-semiconductor vias (TSV). In an embodiment, an IC structure may include a through-semiconductor via (TSV) embedded in a substrate, the TSV having a cap; a dielectric layer adjacent to the substrate; a metal layer adjacent to the dielectric layer; a plurality of vias each embedded within the dielectric layer and coupling the metal layer to the cap of the TSV at respective contact points, wherein the plurality of vias is configured to create a substantially uniform current density throughout the TSV.
