IBM is tapping into its computing know-how to get to the next-generation 22-nanometer chip technology.
Generally, the smaller the geometries, the faster and more power efficient the chip becomes. Both Intel and Advanced Micro Devices are moving their processor lines from 65-nanometer to 45-nanometer technology. (AMD, which does joint chip R&D with IBM, is slated to begin doing this in the fourth quarter.)
After 45nm, comes 32nm, which doesn't present any great manufacturing process hurdles. But 22nm is a different story. And IBM is trying to lead the way--ahead of Intel.
At its most basic, photolithography--the conventional … Read more
