IBM creates nanoscale 3D map with 15nm etching - video

IBM researchers have created a 3D map of the earth so small that 1,000 of them could fit on one grain of salt. The scientists accomplished this through a new, breakthrough technique that uses a tiny, silicon tip with a sharp apex — 100,000 times smaller than a sharpened pencil — to create patterns and structures as small as 15 nanometers at greatly reduced cost and complexity.
