    Abstract: A through silicon via includes a substrate and a conductive plug. The substrate has a hole in a side. The conductive plug is disposed in the hole, and the conductive plug having an upper part protruding from the side, wherein the upper part has a top part and a bottom part, and the top part is finer than the bottom part. Moreover, a through silicon via process formed said through silicon via is also provided, which includes the following step. A hole is formed in a substrate from a side. A first conductive material is formed to cover the hole and the side. A patterned photoresist is formed to cover the side but exposing the hole. A second conductive material is formed on the exposed first conductive material. The patterned photoresist is removed. The first conductive material on the side is removed to form a conductive plug in the hole.

    Abstract: The present disclosure relates to an interposer structure and a manufacturing method thereof. The interposer structure includes a first dielectric layer, a conductive pad, and a bump. The conductive pad is disposed in the first dielectric layer, wherein a top surface of the conductive pad is exposed from a first surface of the first dielectric layer, the conductive pad further includes a plurality of connection feet, and the connection feet protrude from a bottom surface of the conductive pad to a second surface of the first dielectric layer. The bump is disposed on the second surface of the first dielectric layer, and the bump directly contacts to the connection feet. Through the aforementioned interposer structure, it is sufficient to achieve the purpose of improving the electrical performance of the semiconductor device and avoiding the signal being loss through the TSV.
