A commercially available simulation software, Prolith/2, was used to evaluate the aerial image of contact hole arrays and line-space patterns with different pitch sizes. The resolution enhanced by 25%, while the filter shifted the optimum focal position by 5 microns towards the lens. Due to constructive interference between the diffraction rings, secondary maxima appeared between the main peaks. These peaks can be eliminated by means of controlling the spatial coherence the adjacent holes. The filter with a narrow bandwidth introduces a pitch sensitivity and light loss into the system. A pattern can be imaged if the filter transmits the cardinal spatial Fourier components of the mask patterns.
