IBM Plots Path to Denser Chips
IBM researchers say they have found a way to make chips with more than three times the density of today's production chips.IBM researchers say they have found a way to shrink microprocessors and other silicon chips by more than two thirds without requiring fundamentally more expensive process technologies. The company claims it has created "the smallest, high-quality line patterns ever made," with features measuring 29.9 nanometers, using a variant of standard DUV (deep ultraviolet) chip printing methods.
The research group said the appoach can yield "distinct and uniformly spaced ridges" that are 29.9 nanometers wide, which offers a way to make chips with more than three times the density of todays production chips that have recently attained 90-nanometer features. Additionally, IBM said the technique breaks the 32-nanometer barrier thought to have been limiting the density of chips made with optical lithography chip-printing processes.
