    Abstract: A method and apparatus for a conductive bump structure is provided. The conductive bump structure may include a conductive layer and a conductive bump formed over a through via (“TV”). The TV may be formed through a substrate and a passivation layer. The TV may have a top surface extending above a top surface of the passivation layer. The conductive layer may be formed directly over the TV using one or more electroless plating processes. The conductive layer may have sides that may taper from a top surface of the conductive layer to the top surface of the passivation layer. The conductive layer may include a plurality of layers, wherein each layer may be formed using one or more electroless plating processes. The conductive bump may be formed on the conductive layer and may be reflowed to couple the conductive bump to the conductive layer.
