Abstract:
A semiconductor structure comprises a substrate and a metal layer disposed over the substrate. The metal layer comprises a first electrical trace and a second electrical trace. The semiconductor structure comprises a conductive pillar disposed directly on and in electrical contact with the first electrical trace; and a dielectric layer selectively disposed between the metal layer and the conductive pillar. The dielectric layer electrically isolates the second electrical trace from the pillar.
