Sculpting a Nano ‘World’ (Technology Review, 30. April 2010)
“IBM researchers have invented a low-cost and relatively simple fabrication tool capable of reliably creating features as small as 15 nanometers. To show off the tool, 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.
Existing nano-fabrication techniques like electron beam lithography have difficulty making features much smaller than 30 nanometers and are expensive and complex instruments. In contrast, the IBM researchers say their new fabrication tool sits on a tabletop at one-fifth to one-tenth the cost. [...]” [read original article]
