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 …
Witrynaimaging results with a new immersion fluid gave good 65nm Line/Space patterns. However, the minimum exposure time of 20sec is about ten times as needed for water, indicating the need to further reduce the absorbance of the immersion fluid.
