IBM Transitioning to 22nm Chip Fabrication

Intel has already shipped 45nm processors, while AMD is trying to get its 45nm to market. TI is claiming big 45nm performance too. Meanwhile, IBM believes it can lead the market to 32 and then 22nm chip production: “At 22nm, the existing techniques for microprocessor manufacturing useful at the 45nm and 32nm nodes will become obsolete. While currently lithography techniques cannot produce 22nm circuitry, IBM has developed a new approach called Computational Scaling, which will allow for this tiny-scale production. The new technique uses advanced mathematical computation to adjust the shape of the masks and illuminating source during etching.”
