The micrograph shows a scanning ion microscope (SIM) image of the micron-sized arch bridge, prepared by a focused ion beam (FIB) technique. The specimen is extracted from a Si wafer by using a micro-sampling method and mounted on a needle stub of a specimen rotation holder. The 15 µm high gas lamps were also fabricated using FIB by rotating the specimen.
