Lithography pupil
Web10 feb. 2024 · Applied optics The Jones pupil is a full description of imaging properties of projection lenses in optical lithography. The decomposition of the Jones pupil into components with clear physical meanings was studied previously; however, the decomposition method has not been studied systematically. WebDisclosed is a metrology method and associated devices. The method comprises obtaining a first image, said first image being subject to one or more non-isoplanatic aberrations of an optical system used to capture said image; and non-iteratively correcting said first image for the effect of said one or more non-isoplanatic aberrations by performing one or both of: a …
