Narrator: This is Science Today. A new type of transistor has been developed that's so tiny; it's set a world record. Chenming Hu, a professor of engineering at the University of California, Berkeley, says he and his colleagues created a transistor several thousand times smaller than a human hair and it can hold 400 times more devices than currently possible.

Hu: What this means to the industry is that we have shown a way to continue the semiconductor revolution for at least another twenty-five years. Recently, there is the concern and perhaps even a fear that we have come very close to the end of the road for the semiconductor technology. But this research has shown that we are still far away from that limit.

Narrator: Hu says it'll be at least ten years before this new transistor benefits the consumer.

Hu: What we have demonstrated is the principal. The physics that says such small transistors can be manufactured.
