Half pitch lithography

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 …
