WebHigh-NA extreme ultraviolet (EUV) lithography is currently in development. Fabrication of exposure tools and optics with a numerical aperture (NA) equal to 0.55 has started at … WebJan 19, 2024 · To do so, Intel has experimented with High-NA tools since 2024 when it obtained ASML's Twinscan EXE:5000, the industry's first EUV scanner with a 0.55 numerical aperture. WebDec 16, 2024 · But at some point, EUV single patterning will reach the limit. Then, chipmakers must go to EUV double patterning or wait for high-NA EUV. (Today’s EUV lithography scanners incorporate a 0.33 numerical aperture lens, while high-NA lithography utilizes a 0.55 NA lens. Still in R&D, the first high-NA EUV tool is expected in 2024.) implantations
