Abstract: A semiconductor device can include a substrate that has a surface. A via structure can extend through the substrate toward the surface of the substrate, where the via structure includes an upper surface. A pad structure can be on the surface of the substrate, where the pad structure can include a lower surface having at least one protrusion that is configured to protrude toward the upper surface of the via structure.
