Firstly, due to an increasing requirementfor enhanced image resolution. Secondly, because of the ongoing miniaturization of electronic circuits wherefeature sizes are in the order or smaller than the wavelength of light used in the projection imaging system.Lithographic masks are produced by various processes, some of which produce complex shapes with some surfaceroughness on the mask. These shapes a ect both light scattering and image formation.
