Tri-Gate Transistors
Personal computers, smartphones and iPads would never have arrived without the relentless improvement of computer chips. Intel Corp. took a radical step to keep the innovation going, into the third dimension.
The Silicon Valley giant's forthcoming microprocessors incorporate
the most fundamental shift in semiconductor design since 1959. Intel is
building key parts of transistors in each chip using a vertical,
fin-like structure, much as architects developed high-rise buildings
pack more office space in a city.
Intel says the 3-D design, a departure from the flat circuitry of
previous builds, will result in 37% better performance and a 50% drop in
power usage than current chips—helping to ensure that tomorrow's
gadgets will be better than today's.
