Gallery: IBM’s 3D nanoscale breakthrough makes the world a lot smaller

IBM researchers have produced a breakthrough technique that allows scientists to create nanoscale objects. The first mission was to produce the smallest 3D map of the world ever. Using a heated nanoscale silicon tip researchers carved a 22-by-11 micrometer 3D model of the world. At this size, 1000 world maps could fit on a grain of salt. One thousand meters of altitude correspond to roughly eight nanometers (nm).

Using this technique, Researchers created a 25-nanometer high replica of the 4,478-meter tall Swiss peak Matterhorn.

IBM describes the nanoscale tip:

“?The micrograph shows a close-up of the nanoscale silicon tip. This tip, borrowed from atomic force microscopy, measures 500 nanometers in length and only a few nanometers at its apex. It is attached to a cantilever that controllably scans the surface of the substrate material with the accuracy of one nanometer u2013 a millionth of a millimeter. By applying heat and force, the nano-sized tip can remove substrate material based on predefined patterns—operating like a u201cnanomillingu201d machine with ultra-high precision.”

This 25 nanometer replica of the Matterhorn is based on scale of 1:5 billion. Scientists used a nanoscale tip that is 1 million times smaller than an ant to create 2D and 3D patterns and structures as small as 15 nanometers at greatly reduced cost and complexity.

The map is composed of 500,000 pixels, each measuring 20 nm2 and was created in only 2 minutes and 23 seconds.

This is the nanopatterning tool used at IBM Research – Zurich. IBM describes it:

Compared to existing nanostructuring techniques, such as e-beam lithography, the compact and low footprint IBM tool promises improved and extended capabilities at very small feature sizes, but at five to ten times less cost and far less complexity.
