  • Patent number: 11940725
    Abstract: A blankmask for EUV lithography includes a substrate, a reflective layer, a capping layer, and a phase shift layer. The phase shift layer is made of a material containing ruthenium (Ru) and chromium (Cr), and a total content of ruthenium (Ru) and chromium (Cr) is 50 to 100 at %. The phase shift layer may further contain boron (B) or nitrogen (N). The phase shift layer of the present invention has a high relative reflectance (relative reflectance with respect to a reflectance of the reflective layer under the phase shift layer) with respect to a tantalum (Ta)-based phase shift layer and has a phase shift amount of 170 to 230°. It is possible to obtain excellent resolution when finally manufacturing a pattern of 7 nm or less by using a photomask manufactured using such a blankmask.
