IBM announced world fastest transistor : 350GHz !

IBM's new transistor performs nearly 300 percent faster than today's production devices, and it is 65 percent faster than previously reported silicon transistors. A fingernail-sized microchip can hold millions of transistors.

IBM anticipates the new transistor will lead to communications chips with speeds of more than 150 GHz in about two years. The transistor is also expected to result in substantially lower power consumption and lower cost for communications systems and other electronic products.

Bernard Meyerson, IBM fellow and chief technologist, IBM Technology Group, said, "SiGe is imperative for true system-on-chip designs that pull together standard logic circuitry and higher-speed wireless communications circuitry. And while others are introducing their first versions, this is IBM's fifth generation of SiGe technology."

IBM's SiGe chips are built on existing manufacturing lines, allowing the technology to be introduced rapidly and at minimal cost. This has expanded the use of SiGe technology for extending function and battery life in cellular phones and other radio frequency, or wireless, communications products.
