An apparatus incorporating multiple electrical interconnects extending through a substrate (e.g., a silicon wafer), and a method of forming the same. The electrical interconnects convey electrical signals through the substrate to structures mounted on the front side of the substrate. A conductive layer can be used to selectively distribute the electrical signals to the structures. Accordingly, it is not necessary to route electrical signals to the front side of the substrate in order to convey the signals to the structures. A structure can be coupled to multiple electrical interconnects in order to convey electrical signals along redundant paths through the substrate to the structure, improving reliability should one of the electrical interconnects fail.
