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. 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 …
