摘要: A filter for extreme ultraviolet is disclosed. The filter may be formed by a multilayer structure comprising several layers of Yb and Al deposited on a substrate using thermal evaporation. The layers of Yb and Al may be separated by SiO layers, which may act as barriers avoiding interaction between the layers. The multilayer structure may be covered by a SiO protective layer.
