Findings Suggests Immersion is Nearly Ready For Production
Taiwan Semiconductor Manufacturing Company, said that it used immersion lithography tools to produce fully functional 90nm devices. The finding was presented in a keynote speech at the Cymer Lithography Symposium in Semicon Japan on December 1, predating a similar announcement.
TSMC's circuits represent the first data that immersion-based lithography systems are nearing production-ready status.
