Training molecules to draw chips

July 24, 2003 | Source: CNET

Researchers at the University of Wisconsin have developed a way to organize molecules through lithography in “top-down meets bottom-up” system.

The team managed to draw two different types of alternating 24 nanometers long lines into silicon wafers through extreme ultraviolet (EUV) lithography, far smaller than transistors manufactured today.

In the future, this technique could be used to grow longer lines that could be used to retain data inside of magnetic storage devices with 4,000 gigabytes of memory.
