|Abstract:||The dependencies of lithographic factor k1 on illumination conditions were discussed. A modified Rayleigh's equation of coherencies on lithographic resolutions was proposed for the study. It was found that the areas of different diffraction order were captured by the pupil and were evaluated as function of wavelength. The results show that the extension of Rayleigh's equations was capable of mapping out the forbidden pitch locations for any design rules and optimizing the rule of focus.|
