Can Silicon Be Turned Into The Teeniest Transistors?

Make transistors small enough, and all kinds of good things happen. For example, if a transistor can be shrunk to 0.1 micron wide, or 0.1% the diameter of a human hair, electrons will shoot across it without bumping into lots of other subatomic particles. These collisions are what slow down signals in chips and generate most of the heat. Thus, tighter dimensions may yield chips that process data at superfast speeds without creating so much heat that they melt.
