Abstract:
1. A semiconductor device, comprising: a substrate; a plurality of conductive pads formed in consecutive conductive layers, the plurality of conductive pads aligned and arranged one above another over the substrate, wherein the plurality of conductive pads comprises a first conductive pad and a second conductive pad, the first conductive pad is above the second conductive pad, a redistribution layer extends the second conductive pad, and the first conductive pad is not extended by a redistribution layer; a bump structure formed on the first conductive pad and electrically coupled to the plurality of conductive pads; and a dielectric layer extending into a gap between peripheral parts of the first and second conductive pads, wherein middle parts of the first and second conductive pads are in direct contact with each other, and wherein the redistribution layer and the second conductive pad comprise different conductive materials.
