In this paper we present a methodology for DUV lithography simulator tuning by resist profile match-ing. At these wavelengths, the photomask pattern is normally etched into a chrome layer on a glass substrate. DUV. 20 May 2020 DUV resist technology saw dramatic adjustments in chemistry when 248 nm lithography came to the market. – 1985: Mercury lamp i-line (365 nm) – 2002: ArF laser (DUV: 193 nm) – 2011 (?): Tin Plasmas (EUV: 13. duv lithography
