An integrated circuit includes a plurality of tiles. Each individual hanger includes a hanger spacer which is easily removable and interchangeable with hanger spacers of a different size. The method includes determining, at a processor of the mobile communication device, whether the dialed digits are associated with an action based on action information stored at a memory of the mobile communication device. The phospholipid and detergent molecules and their micelles may then be removed by dialysis. The second electrodes is positioned over the first electrodes and supported through the patterned support layer such that an air gap with identical thickness is produce between every pair of second electrode and first electrode. A lateral Schottky diode and an n-MOST can be formed within a single voltage-sustaining region.
