Lithography coherence factor
WebIn the parlance of lithography, the illumination coherence factor is typically cho-sen to be approximately 0.7, where is often de-scribed as the ratio of the illumination divergence to the lithographic optic object-side numerical aperture NA . Under the condition where an incoherent source is imaged to the lithographic optic object plane WebThe acceleration of integrated circuit miniaturization is challenging lithographers to push the limits of optical lithography by ever more precise engineering and innovations. As IC device dimensions grow smaller, circuits outpace the introduction of shorter exposure wavelengths and higher numerical aperture lenses, increasing the importance of resolution …
