Methods of patterning features, methods of patterning material layers of semiconductor devices, and methods of manufacturing semiconductor devices are disclosed. The first polishing step is then followed by a second step of chemical-mechanical polishing of the surface of the germanium layer carried out with a second polishing solution having an alkaline pH. Each person reads the tag at their seated position using a personal interrogator, which may be incorporated into a cellular telephone. A first bonnet piece forms a first leg of the bonnet, and a second bonnet piece forms a second leg and a base of the bonnet. This composition is excellent in heat resistance and melt-mold processability. The motorcycle also has an alarm system that uses the same acceleration sensor to detect vibrations indicative of a potential theft of the vehicle.
