Abstract
Multilayer deposition is one of the key technologies for the fabrication of reticle blanks for extreme ultraviolet lithography (EUVL). Molybdenum/silicon (Mo/Si) multilayers deposited on mask blanks must have a high reflectance and a low defect density. To achieve this, ASET has developed a deposition system that employs ion beam sputtering (IBS). This paper presents some preliminary experimental results, such as the EUV reflectance and defect density of Mo/Si multilayers deposited with this system.
