Immersion lithography 浸潤式顯影技術
Witryna8 lip 2013 · Because the development of extreme ultraviolet (EUV) lithography is behind schedule throughout the industry, TSMC will continue to use its argon fluoride (ArF) immersion lithography (which relies on 193-nm-emitting ArF excimer lasers), which the company introduced for the 40 nm process, for 28, 20, 16, and 10 nm processes. … WitrynaThe current work in immersion lithography started in 2001 with the report of Switkes and Rothschild. Although their first proposal was at 157 nm wavelength, their report in …

WitrynaImmersion lithography [1-4] has changed the way we view defectivity issues at the wafer edge significantly. During the immersion exposure se quence, the wafer edge is in contact with the water from the immersion hood (IH), introducing additional concerns beyo nd direct contact of resist with the scanner.
Witryna21 sty 2024 · Jan 14, 2024. #2. The 157nm immersion approach got us to sub-40nm lithography, however starting at sub-28nm we had to start using multi-patterning, or multiple masks per layer. EUV has a 13.5 nm wavelength and this allows the industry to do many of the critical layers in 11nm and smaller nodes. Mask costs are high, and …
Witryna193 nm immersion lithography optical projection systems using conventional UV optical materials and water as the immersion fluid, with planar lens/fluid interfaces, have a practical numerical aperture (NA) limit near 1.3. The bottleneck for pushing the NA further is the refractive index of the final lens element.
