Intel Increases Transistor Speed by Building Upward

Intel announced on Wednesday that it had again found a way to make computer chips that could process information more quickly and with less power in less space.The transistors on computer chips — whether for PC’s or smartphones — have been designed in essentially the same way since 1959 when Robert Noyce, Intel’s co-founder, and Jack Kilby of Texas Instruments independently invented the first integrated circuits that became the basic building block of electronic devices in the information age.

Intel Corp. showed off what it called the most radical shift in semiconductor technology in more than fifty years, a design that could produce more powerful chips for gadgets without taxing their batteries.The company plans to change a key part of each chip into a vertical, fin-like structure, a similar principle to the way high-rise buildings pack more office space in a city. The parts being changed — transistors — are the building block of nearly all electronic products; today’s microchips can contain billions of the tiny switching elements.

Intel has unveiled its next generation of microprocessor technology, code named Ivy Bridge.The upcoming chips will be the first to use a 22 nanometre manufacturing process, which packs transistors more densely than the current 32nm system.Intel said it would also be using new Tri-Gate “3D” transistors, which are less power hungry.Rival chip manufacturers including AMD and IBM are understood to be planning similar designs.
