    Abstract: The present interposer makes it possible to tailor the coefficient of thermal expansion of the interposer to match components to be attached thereto within very wide ranges. The semiconductor interposer, includes a substrate of a semiconductor material having a first side and an opposite second side. There is at least one conductive wafer-through via including metal. At least one recess is provided in the first side of the substrate and in the semiconductor material of the substrate, the recess being filled with metal and connected with the wafer-through via providing a routing structure. The exposed surfaces of the metal-filled via and metal-filled recess are essentially flush with the substrate surface on the first side of the substrate. The wafer-through via includes a narrow part and a wider part, and contact elements are provided on the routing structure having an aspect ratio, height:diameter,

    Abstract: The invention relates to a semiconductor structure, comprising a substrate of a semiconductor material having a first side (FS) and an opposite second side (BS). There is at least one conductive wafer-through via (V) comprising metal, and at least one recess (RDL) provided in the first side of the substrate and in the semiconductor material of the substrate. The recess is filled with metal and seamlessly connected with the wafer-through via. The exposed surfaces of the metal filled via and the metal filled recess are essentially flush with the substrate surface on the first side of the substrate. There is also provide an interposer comprising the above structure, further comprising contacts for attaching circuit boards and integrated circuits on opposite sides of the interposer. A method of making the structure is also provided.
