Treating a capping layer of a mask |
摘要 |
A method for forming a lithography mask includes forming a capping layer on a reflective multilayer layer, the capping layer comprising a first material, forming a patterned patterning layer on the capping layer, and introducing a secondary material into the capping layer, the secondary material having an atomic number that is smaller than 15. |
