Latent Image Characterization by Spectroscopic Reflectometry in the Extreme Ultraviolet

The application of spectroscopic EUV reflectometry for characterizing the latent image of a line grating is investigated. Numerical simulations with JCMsuite are performed to compute the reflectance of latent images of line gratings and simulations to analyze latent image gratings with a surface topography.
