Abstract
Disclosed are techniques for correcting the EUV crosstalk effects. Isolated mask feature component diffraction signals associated with individual layout feature components are determined based on a component-based mask diffraction modeling method such as a domain decomposition method. Mask feature component diffraction signals are then determined based on the isolated mask feature component diffraction signals, layout data and predetermined crosstalk signals. Here, the predetermined crosstalk signals are derived based on mask feature component diffraction signals computed using an electromagnetic field solver and the component-based mask diffraction modeling method, respectively. The mask feature component diffraction signals are then used to process layout designs.
