Abstract:
1. A semiconductor device comprising: a silicon substrate having a first side and a second side; a conductive interconnect extending from a first side toward a second side of the silicon substrate, the conductive interconnect having a first end proximate the first side of the silicon substrate and a second end proximate the second side of the silicon substrate; a first dielectric structure proximate the first side of the silicon substrate; a first metal routing structure at the first dielectric structure, the first metal routing structure being at least partially in the first dielectric structure; a second dielectric structure having at least a first opening generally corresponding to the first metal routing structure, a second opening generally corresponding to the conductive interconnect, and a third opening; and a first conductive portion in the first opening, a second conductive portion in the second opening, and a second metal routing structure in the third opening.
