Web5 apr. 2024 · Minimum pitch resolution. A lithography tool is specified by the wavelength it uses, e.g., 193 nm for ArF, 13.5 nm for EUV, as well as its numerical aperture, i.e., the power of its final optic element (lens for ArF, KrF, i-line, mirror for EUV). The formula for the ideal minimum pitch between two lines in an array is. WebThe direct correlation of lithographic resolution and illumination wavelength, eq’n 4, has traditionally been the main resolution reduction enabler.
