ELECTRONICS:
Terribly Tiny Transistor Unveiled
Dennis Normile
TOKYO--A transistor's gate--the narrow electrode that controls the flow of electrons through the device--can be made only so small, or else electrons will manage to sneak through even when the device is off. But at a recent conference in Japan, a group at NEC's Fundamental Research Laboratories in Tsukuba announced that, by combining a novel design with high-precision techniques for carving semiconductors, it has developed an experimental transistor with a gate 20 times smaller than in the transistors found on the densest commercially available chips.
