A method of immersing a substrate into electrolyte solution for electroplating, the method comprising connecting an electric source between an anode immersed in the electrolyte solution and a seed layer formed on the substrate. A first voltage level of the seed layer is biased to be equal to, or more positive than, a second voltage level of the anode. The substrate is then immersed into the electrolyte solution.
