Lithography resist

In lithography, decreasing the wavelength of light source is the most efficient way to achieve higher resolution. Photoresists are most commonly used at wavelengths in the ultraviolet spectrum or shorter (<400 nm). For example, diazonaphthoquinone (DNQ) absorbs strongly from approximately 300 nm to 450 nm. The absorption bands can be assigned to n-π* (S0–S1) and π-π* (S1–S2) transitions in the DNQ molecule. In the deep ultraviolet (DUV) spectrum, the π-π* ele… WebEstimating resist parameters in optical lithography using the extended Nijboer-Zernike theory Peter Dirksen Philips Research Leuven Kapeldreef 75 B-3001 Leuven, Belgium E …
