Limits of Resolution: The Rayleigh Criterion Wave Optics

WebApr 7, 2024 · The Rayleigh criterion defines the resolution between two features. For an immersion lithography system, the wavelength is 193 nm, and the numerical aperture is 1.35, giving a minimum interspot distance of 87 nm. This distance might be reduced a little by the use of attenuated phase shifting masks; the improvement depends on the transmssion of ...
