WebOct 5, 2024 · Description. Extreme ultraviolet (EUV) lithography is a soft X-ray technology, which has a wavelength of 13.5nm. Today’s EUV scanners enable resolutions down to 22nm half-pitch. In a system, an EUV light source makes use of a high power laser to create a plasma. This, in turn, helps emit a short wavelength light inside a vacuum … WebJun 1, 2010 · The resolution record in interference lithography has been reported as 22-nm half pitch, albeit at the now discredited 157-nm wavelength and with a special …

WebJan 8, 2024 · Optical Lithography: the fine print of the Abbe criterion. The "brick wall" resolution limit of an optical lithography system is the Abbe criterion recited as a formula: minimum half-pitch = 0.25 ... WebNov 29, 2011 · This is comparable to conventional production-level photolithography but at a much higher resolution of 22 nm half-pitch size.

WebJan 2, 2024 · Sometimes the half-pitch is used. Unsurprisingly, that is half the pitch, and if the width and spacing on the layer are the same, then it will equal them both. The fundamental equation of lithography is that the resolution (half-pitch this time) is k 1 × λ ÷ NA where: k 1 is the Rayleigh parameter, which is a measure of the lithography ... WebMar 18, 2016 · EUV interference lithography records the interference pattern of two diffracted, coherent light beams, where the pattern resolution is half the diffraction grating resolution. The fabrication of diffraction grating masks by e-beam lithography is restricted by the electron proximity effect and pattern transfer limitations into diffraction efficient … WebMar 20, 2015 · We have synthesized a new resist molecule and investigated its high-resolution capability. The material showed resolved line-spaces with 14 nm half-pitch (hp) and the potential to pattern 11 nm hp features. Line edge roughness values as low as 3.15 nm were seen in optimized formulations.
