EUV laser has a wavelength of 13.9 nm, and this laser wavelength is close to the wavelength of EUV lithography (λ = 13.5 nm). The irradiation system has an intensity monitor based on the Mo/Si multilayer beam splitter. This intensity monitor provides the irradiation energy onto sample surface. So it is possible to examine and confirm damage/ablation thresholds of optical elements and doses for sensitivity of resist materials, which have the same specifications of those in the EUV lithography., 16th International Conference on X-Ray Lasers (ICXRL 2018)}, title = {EUV laser irradiation system with intensity monitor}, year = {2018} }
