发明名称 Reflective mask blank for EUV lithography, and substrate with functional film for the mask blank
摘要 Provided are a substrate with a conductive film for an EUV mask blank in which the generation of particles due to abrasion between an electrostatic chuck and the substrate is prevented; and a substrate with a multilayer reflective film and an EUV mask blank each employing such a substrate with a conductive film. A substrate with a conductive film to be used for producing a reflective mask blank for EUV lithography, the conductive film containing chromium (Cr) and nitrogen (N), the average concentration of N in the conductive film being at least 0.1 atomic % and less than 40 atomic %, the crystal state of at least a surface of the conductive film being amorphous, the sheet resistance of the conductive film being at most 27 &OHgr;/□, and the surface roughness (rms) of the conductive film being at most 0.5 nm.
