A new tool makes etching extremely small features relatively easy and cheap

摘要

IBM researchers have invented a low-cost and relatively simple fabrication tool capable of reliably creating features as small as 15 nanometres. The researchers at IBM's Zurich lab made a three-dimensional map of the Earth so small that 1,000 of them would fit onto a single grain of salt.rnNano-cartography: IBM Zurich researchers have created a tiny map of the world; 1,000 such maps could fit on a grain of salt. The map was drawn using a new nano-fabrication tool capable of creating features as small as 15 nanometres.
