The present invention provides a composition for use in forming a porcelain enamel coating having a metallic appearance. After a bank is formed, an exposed anode surface is wiped using a PVA -based porous substance or the like to level the surface and remove dusts from the surface. First and second resilient guide members extend laterally from the boot member adjacent the free end, and are parallel, coplanar, and separated by a fixed distance. The channel is transitioned from full service mode to partial service mode when the channel is in full service mode and monitoring detects that the modulation mode is less than or equal to the trigger value. A second rotary shaft is rotatably supported in the jacket, and is operatively connected to the treatment tool at one end and to the first rotary shaft at the other end via a gear. Among other devices, recessed access devices can be formed by the method for memory arrays.
