providing a first gel on a portion of the surface of the substrate;
providing a source element comprising the plating material over the first gel, wherein the source element comprises a source gel, different from the first gel, and the plating material comprises metal ions suspended in the source gel;
providing a conductive layer over the source element; and
applying an electrical current signal to the conductive layer to cause the plating material to be deposited on the surface of the substrate.
2. The method of claim 1 further comprising subdividing the substrate.
3. The method of claim 2 , wherein the subdividing the substrate comprises cutting the substrate into chip sizes.
