World's Smallest Snowman is Just 3 Microns Tall
Western Nanofabrication Facility. At only 3 microns tall, the snowman was fabricated from three 0.9-micron silica spheres stacked by using electron beam lithography. The snowman's eyes and mouth were etched with a focused ion beam, whereas the nose and arms were sculpted with platinum.
