An interconnection system is provided for a solid-state device. The
solid-state that includes, a first layer, multiple devices and a first
face. A second layer is bonded to the first face at a bonded face of the
second layer that faces the first face. Electrically conductive bonds are
between the first and second faces. Conductive paths are on the bonded
face of the second layer and connect two or more of the conductive bonds.
