Abstract:
1. A semiconductor system, comprising: a first semiconductor substrate having a first substrate material; a first conductive material carried by the first semiconductor substrate and forming a penetrating structure; a second semiconductor substrate having a second substrate material with a first surface, a second surface facing away from the first surface, and a through-substrate via extending from the first surface to the second surface along a via axis; and a second conductive material carried by the second semiconductor substrate and having a pre-formed recess positioned along the via axis, the penetrating structure being received in the recess and being in mechanical and electrical contact with the second conductive material, the second conductive material being a first distance from the via axis at a first position in the recess and a second distance larger than the first distance from the via axis at a second position in the recess, wherein the second position is deeper in the recess than the first position.
