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

"We’ve 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 world’s smallest working device that had been fabricated using optical lithography, which is the technology that’s 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."
