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 … Witryna2 sty 2024 · Lithography was originally a way of printing using a flat stone. Lithos (or λίθος) is the Greek for stone. ... This was known as 193i, with the "i" standing for "immersion" and the whole approach known as immersion lithography. This all came to an end at 28nm since it was impossible to manufacture better lenses, and we had …
