An IBM led alliance on Monday said customers now have the option of designing into future products the group's jointly developed 32-nanometer chips, which are expected to be more power efficient than current-generation microprocessors. The latest processors use transistors built with a new material known as "high-k/metal gate," which makes it possible to shrink the size of transistors to 32 nanometers. The latest chips today use 45-nanometer transistors. By reducing the size further, chipmakers can get more of the devices on a piece of silicon, which translates into greater power efficiency. IBM has manufactured chips using high-k/metal gate at its 300-millimeter semiconductor fabrication facility in East Fishkill, N.Y. IBM partners in the initiative include Chartered Semiconductor Manufacturing, Freescale, Infineon Technologies, Samsung Electronics, STMicroelectronics, and Toshiba. Intel is not part of the alliance, but the chipmaker is developing its own chips using similar materials.
