The micrograph shows a secondary electron(SE) image of the world's smallest tower prepared by a FIB (Focused Ion Beam) technique.
The specimen is extracted from a Si wafer by using a micro-sampling method and mounted on a needle stab of a specimen rotation holder. A towered shape is made by rotating the specimen. Although the FIB was initially developed for fixing and evaluation of semiconductor devices, such micromanipulation technologies have been made a further progress.
First Place (Field 1: Non-biology)
