Microelectronics Faces Limits As Chips Shrink Further
Patrick Young reports from Washington on the micrometer barrier in chip design. Researchers aim for lines far thinner than a human hair to boost density, energy efficiency, and performance, with 256K RAM giving way to megabit RAM and lines potentially ten times smaller than today. IBM’s Robert Keyes notes shrinking devices enables higher integration, but the field confronts difficult fabrication challenges.
