This is Science Today. Researchers at the University
of California, Berkeley have essentially set the stage
for the future of semiconductor technology by developing
the tiniest transistor yet. Chenming Hu, a professor
of electrical engineering and computer sciences, says
their breakthrough has been to change the design of
the transistor switch, which controls the flow of
current in electronic devices.
What we have done is to show that the switch can be
made much smaller than commonly thought possible.
The size of the switch in the transistor that we fabricated
is less than one part in ten thousandths of a human
By making components smaller, electronics become cheaper
It's cheaper because it's simply cheaper to make a
larger number of chips on a given piece of silicon
wafer. So the smaller we can make the transistors,
the smaller we can make the chips, than the chips
will be cheaper.
