Researchers have developed a gradient-based inverse lithography technology (ILT) for extreme ultraviolet (EUV) masks. This new framework integrates a differentiable waveguide method with a waveguide neural operator (WGNO) to reconstruct the mask's absorber permittivity. Numerical simulations demonstrate that this approach can successfully generate mask structures capable of achieving desired field patterns on the wafer. AI
