Solder bump connections and methods for fabricating solder bump connections. The method includes forming a layer stack containing first and second conductive layers, forming a dielectric passivation layer on a top surface of the second conductive layer, and forming a via opening extending through the dielectric passivation layer to the top surface of the second conductive layer. The method further includes forming a conductive plug in the via opening. The solder bump connection includes first and second conductive layers comprised of different conductors, a dielectric passivation layer on a top surface of the second conductive layer, a via opening extending through the dielectric passivation layer to the top surface of the second conductive layer, and a conductive plug in the via opening.
