摘要:
A composite extreme ultraviolet light (EUV) mask absorber structure and method are disclosed to address the structural and processing requirements of EUV lithography. A first mask absorber layer anisotropically etched with minimal etch bias at a relatively fast etch rate, is combined with a highly-selective second mask absorber layer, to produce a mask absorber with desirable hybrid performance properties.
