Among other things, one or more systems and techniques for promoting metal plating profile uniformity are provided. A magnetic structure is positioned relative to a semiconductor wafer that is to be electroplated with metal during a metal plating process. In an embodiment, the magnetic structure applies a force that decreases an edge plating current by moving metal ions away from a wafer edge of the semiconductor wafer. In an embodiment, the magnetic structure applies a force that increases a center plating current by moving metal ions towards a center portion of the semiconductor wafer. In this way, the edge plating current has a current value that is similar to a current value of the center plating current. The similarity between the center plating current and the edge plating current promotes metal plating uniformity.
