Publication number: 20250147414Abstract: Methods and materials for improving the hardness of a metallic photoresist used in EUV photolithography are disclosed. A metallic cross-linker is used with the metallic photoresist. The cross-linker comprises a metal core and a plurality of ligands. The ligands may comprise at least one vinyl group or at least one acetylene group; or comprise an acrylate; or comprise a cinnamate; or be unable to participate in a crosslinking reaction. Upon radiation exposure, the ligands separate from the metal core, and the metal core can crosslink, or the ligands may crosslink.
