Lithography light source
WebIn DUV lithography, the light source typically has a wavelength of 248 nm (KrF laser) or 193 nm (ArF excimer laser). At these wavelengths, the photomask pattern is normally etched into a chrome layer on a glass substrate. The numerical aperture of the imaging optics (NAo) can range from 0.5 to greater than 1 for immersion lithography techniques. Web1 jun. 2015 · While the lithography exposure tool, or scanner, has been extensively characterized to understand how the various input parameters (focus, dose, overlay, and …
