Hi, Everyone I am trying to do electroplating copper for about 2 to 5 um thickness on top of the sacrificial layer of polymer. Right now my lab has EPI E-Brite Ultra Cu solution, multimeter, hotplate, magnetic stiring bar,voltage source, electrode clamps. I connected the circuits with required current (10ASF), but seems the copper didn't grow on the seed layer which is also copper. I went back to the instruction sheet of the E-Brite Ultra Cu, it looked much more complicated than I thought. Does anybody have the experience using the E-Brite Ultra Cu solution ? Please give me some brief description of how to us it. My another question is: Can I use other materials as seed layer such as aluminium ? Any help will be appreciated. If you have experience with other plating solutions, it is also welcome, I don't have to restrain to one only material. Thanks J.J.
