Claim 8:
9. A semiconductor device comprising:
an upper signal distribution structure comprising an upper structure top side and an upper structure bottom side;
a lower signal distribution structure comprising a lower structure top side and a lower structure bottom side, wherein the upper structure bottom side is coupled to the lower structure top side;
a semiconductor component comprising a component top side and a component bottom side, wherein the component bottom side is coupled to the upper structure top side; and
a conductive interconnection structure coupled to the lower structure bottom side; and
wherein the lower signal distribution structure comprises a dielectric lower layer and a conductive lower layer;
wherein the conductive lower layer extends into an opening in the dielectric lower layer and towards the upper signal distribution structure;
wherein the lower signal distribution structure comprises an under bump metal structure that has a concave shape that opens downward;
wherein the under bump metal structure comprises a bump upper side and a bump lower side; and
wherein the bump upper side is coupled to the lower structure bottom side.
