A system and method for forming contacts is provided. An embodiment comprises forming the contacts on a substrate and then coining the contacts by physically shaping them using, e.g., a molding chamber. The physical shaping of the contacts may be performed using a patterned portion of the molding chamber or else by placing a patterned stencil around the contacts prior before a force is applied to physically reshape the contacts. The contacts may be reshaped into a cylindrical, oval, cuboid, or rectangular shape, for example.
