Claim 2:
3. The method of claim 1, wherein forming the layers of the upper signal distribution structure comprises:
forming a first dielectric layer of the upper signal distribution structure;
forming a first conductive layer of the upper signal distribution structure on the first dielectric layer of the upper signal distribution structure such that the first conductive layer of the upper signal distribution structure extends into a first opening in the first dielectric layer of the upper signal distribution structure and towards the lower signal distribution structure;
forming a second dielectric layer of the upper signal distribution structure on the first conductive layer of the upper signal distribution structure; and
forming a second conductive layer of the upper signal distribution structure on the second dielectric layer of the upper signal distribution structure such that the second conductive layer of the upper signal distribution structure extends into a second opening in the second dielectric layer of the upper signal distribution structure and towards the lower signal distribution structure.
