Abstract
A wire bond design integrated circuit with a substrate having a front side and an opposing back side. Circuitry is disposed on the font side. Electrically conductive vias are disposed through the substrate from the front side to the back side, and are electrically connected to the circuitry such that the electrically conductive vias provide power and ground services only for the circuitry. Bonding pads are disposed on the front side, and are electrically connected to the circuitry such that the bonding pads provide signal communication only for the circuitry.
