IBM boffins create a 25nm rendering of the Matterhorn
NEVER MIND writing the Lord's Prayer on a grain of rice, scientists at IBM have worked out a method for making 3D pictures at the atomic scale.
According to Science magazine, the team says they have come up with a system that outperforms e-beam lithography in speed and resolution, at lower cost.
To show off what they can do, the team fabricated a 22µ by 11µ map of Earth and a 25µ high 3D rendering of the 14,692 foot tall Matterhorn.
Each image was fabricated at a scale of 5 billion to 1 and was drawn with a silicon tip similar those used in atomic-force microscopes. Each was 500 nanometers in length and only a few nanometers wide at its apex.
Biggish blue said that it can scan the surface of any substrate with 1nm accuracy. The technology will end up under the bonnets of gear to prototype nanoscale CMOS electronics, optical components and meta-materials.
It can also make shape-matching templates that direct the self-assembly of nanorods or nanotubes. µ

here's a picture, especially for you.

or it didn't happen.
the 25 was height, the other 2 were width and length
I find it hard to believe both models are of the same scale, given the Matterhorn is modeled at 25u high and the earth as 22u wide.
Wow, so we might have another couple decades to go where things keep shrinking.
I figured that the carbon nanotubes would be needed a ton sooner.
