An integrated circuit structure includes a semiconductor substrate having a front side and a backside. A through-silicon via (TSV) penetrates the semiconductor substrate, wherein the TSV has a back end extending to the backside of the semiconductor substrate. A redistribution line (RDL) is formed over the backside of the semiconductor substrate and connected to the back end of the TSV. A passivation layer is over the RDL with an opening formed in the passivation layer, wherein a portion of a top surface of the RDL and a sidewall of the RDL are exposed through the opening. A metal finish is formed in the opening and contacting the portion of the top surface and the sidewall of the RDL.
