An integrated circuit includes a conductive pad disposed over a substrate. A first passivation layer is disposed over the conductive pad. A second passivation layer is disposed over the first passivation layer. A stress buffer layer is disposed over the second passivation layer. A conductive interconnect layer is over and coupled to the conductive pad and over the stress buffer layer with the conductive interconnect layer adjoining sidewalls of the first passivation layer and the stress buffer layer.
