Abstract:
1. A method of electroplating a substance over a semiconductor substrate, comprising: forming a first electrically conductive material over a first region of the semiconductor substrate and forming a second electrically conductive material over a second region of the semiconductor substrate; flowing an electrical current through the first and second electrically conductive materials while exposing the first and second electrically conductive materials to an electrolytic solution; and electroplating a substance onto the first electrically conductive material during the flowing of the electrical current through the first and second electrically conductive materials and while exposing both of the first and second electrically conductive materials to the electrolytic solution; the substance being formed primarily on the first of the electrically conductive materials such that the substance is thicker on the first electrically conductive material relative to any of the substance on the second electrically conductive material.
