Image a line/space grating through a partially coherent projection lens and predict what actually prints: the aerial-image cross-section, printed CD, image contrast and NILS, the k1 factor and Rayleigh resolution limit, depth of focus and exposure latitude. Explore numerical aperture, partial coherence, off-axis illumination (annular / dipole), attenuated phase-shift masks, defocus, and EUV vs 193i immersion. Runs on the ChipFoundryServices distributed compute pool. Reduced-order educational model. See also the etch, deposition and inference simulators and the compute-pool status.
