The SXRL has a wavelength of 13.9 nm, and this laser wavelength is close to the wavelength of extreme ultraviolet (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 EUV optical elements and doses for sensitivity of resist materials, which have the same specifications of those in the EUV lithography., SPIE Photonics West LASE LAMOM}, title = {Development of soft x-ray laser irradiation beamline for ablation and damage study}, year = {2019} }
