Unit 4.1 Minidoc: Miniaturization
Miniaturization has enabled the creation of ultra small
electronic parts, smaller than the wavelength of light.
This requires new polymeric materials, and an understanding
of forces acting at the atomic level.

The chemistry of miniaturization
Ultra miniature parts
"Weve been able to demonstrate
a working flash memory cell, having 60nm features. It was
done a little over a year ago, and at the time it was the
worlds smallest working device that had been fabricated
using optical lithography, which is the technology thats
used in most device fabrication facilities today. We are
able to get features as small as 60nm, which, when you think
about it, is about one third the width of the wavelength
of light. When I started at Bell Laboratories, a little
over 20 years ago, the conventional wisdom was that you
could never produce something smaller than the wavelength
of light, simply because of physical principles, diffraction
facts which would prevent you from doing that."
