Web57.3 OPTICAL PROPERTIES OF LITHOGRAPHIC POLYMERS AND PHOTORESISTS Polymers for photoresists must meet stringent transpar-ency requirements at the imaging wavelength in order to deliver superior resolution and image quality. Suitable poly-mer platforms have been identified for I-line (365 nm) and 248 nm DUV lithography. They … Web23 mrt. 2024 · Lithography processing. Lithography processing is a series of processing steps used to pattern masks and samples with photoresist prior to other processing steps (e.g. deposition, etching, doping). There are a variety of lithography processes that are available in the LNF. This page specifically talks about optical (UV) lithography. WebOver the past decade, researchers have shattered the traditional view of the diffraction limit. Using new techniques, they have obtained resolution far smaller than the wavelength of light excitation or emission. Similar concepts are now being applied to photolithography, making it possible to create nanoscale features in a photoresist using visible or near-infrared light. lalelu ball 2023
