Rayleigh criterion 공식
WebRayleigh's Criterion is usually applied to circular apertures, where the criterion for resolution is when the center of one Airy disk pattern falls on the first minimum of the Airy disk pattern of the second source. The angular separation θ is then. θ = ( 1.22 λ ) / D. where λ is the wavelength of light, and D the aperture diameter. WebThis figure plots the ratio of the numerical apertures of the condenser and objective versus the minimum resolved distance between Airy patterns (Rayleigh criterion) in units of wavelength divided by the objective aperture. When two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA

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 ...
