    摘要: A semiconductor device having one or more through-silicon vias (TSVs) is provided. The TSVs are formed such that sidewalls of the TSVs have a scalloped surface. In an embodiment, the sidewalls of the TSVs are sloped wherein a top and bottom of the TSVs have different dimensions. The TSVs may have a V-shape wherein the TSVs have a wider dimension on a circuit side of the substrate, or an inverted V-shape wherein the TSVs have a wider dimension on a backside of the substrate. The scalloped surfaces of the sidewalls and/or sloped sidewalls allow the TSVs to be more easily filled with a conductive material such as copper.

    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.
