Abstract
The printability of both amplitude and phase defects has been investigated in proximity to absorber lines with widths corresponding to the 45 nm and 32 nm nodes. The single surface approximation was used to simulate defects within the multilayer coating. The printability of Gaussian phase defects was simulated versus width and height and location with respect to the absorber line. For narrow defects the worst location was found to be next to the absorber line, while wide defects had the greatest effect when centered under the absorber. A uniform flare was found to have little effect on the critical defect size. The results of these simulations are aimed at defining the critical defects for EUVL masks designed for the 32 nm node.
