Abstract
An apparatus includes a first metal layer, a second metal layer and a dielectric material. The first metal layer has a first thickness and a second thickness less than the first thickness, and the first metal layer comprises a first interconnect having a first thickness. The dielectric material extends between the first and second metal layers and directly contacts the first and second metal layers. The dielectric material includes a via that extends through the dielectric material. A metal material of the via directly contacts the first interconnect and the second metal layer.
