Web13 mei 2024 · Semiconductor manufacturers want the next big thing: to adopt high numerical aperture lithographic processes using extreme ultraviolet light to print smaller circuits. Andy Extance finds out more Imec is using a high harmonic generation laser with anamorphic mirrors to explore high NA EUV challenges WebAbstract High-numerical-aperture (NA) anamorphic imaging projection objectives are the industrial choice for extreme ultraviolet lithography under the advanced technology node. The illumination system has to match the elliptical entrance pupil of the high-NA projector.

Web1 mrt. 1992 · This paper explores fundamental imaging phenomena that become appreciable as the numerical aperture (NA) of imaging lenses increase beyond 0.5. A … In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one material to another, provided there is no refractive power at the interface. The exact definition of th… did whitebeard beat kaido
