    摘要: A through silicon via structure includes a top pad and a vertical conductive post that is connected to the top pad. The top pad covers a wider area than the cross section of the vertical conductive post. An interconnect pad is formed at least partially below the top pad. An under layer is also formed at least partially below the top pad. At least one dummy structure connects the top pad and the under layer to fasten the top pad and the interconnect pad.

    摘要: An integrated circuit structure includes a substrate; a through-silicon via (TSV) in the substrate, the TSV being tapered; a hard mask region extending from a top surface of the substrate into the substrate, wherein the hard mask encircles a top portion of the TSV; dielectric layers over the substrate; and a metal post extending from a top surface of the dielectric layers to the TSV, wherein the metal post comprises same materials as the TSV.
