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… Web3 mrt. 2024 · The lithographic performance was affected by many factors, such as the compositions of the photoresist, baking temperature, spin coating, photoacid loading, exposure dose, development, and so on.
