Abstract:
1. An integrated circuit comprising: a substrate; a top conductive layer, the top conductive layer having at least one bonding pad and a sub-layer of relatively stiff material, wherein the sub-layer of relatively stiff material is relatively stiff compared to a remainder of the top conductive layer; one or more intermediate conductive layers formed between the top conductive layer and the substrate; layers of insulating material separating the top conductive layer from the one or more intermediate conductive layers and separating layers of the more intermediate conductive layers, one layer of the layers of insulating material is relatively thick compared to the other layers of insulating material and is located between the top conductive layer and an intermediate conductive layer closest to the top conductive layer; and devices formed in the integrated circuit, wherein at least the intermediate conductive layer closest to the top conductive layer is adapted for functional interconnections of select devices under the bonding pad.
