Claim Text:
1. A method of forming a chip with a though-silicon-via (TSV) electrode, comprising: providing a substrate, wherein the substrate has a first surface and a second surface; performing a thinning process from the second surface of the substrate thereby making the second surface become a third surface; forming a penetration via which penetrates through the first surface and the third surface; forming a patterned material layer on the third surface of the substrate, wherein the patterned material layer has an opening exposing the penetration via; and simultaneously filling a conductive layer into the penetration via and the opening such that the conductive layer in the penetration via becomes a TSV electrode and the conductive layer in the opening becomes a surface conductive layer, wherein the surface conductive layer is a redistribution layer.
