PHOTOMASK BLANK AND MAKING METHOD, PHOTOMASK, LIGHT PATTERN EXPOSURE METHOD, AND DESIGN METHOD OF TRANSITION METAL/SILICON BASE MATERIAL FILM
摘要:
A photomask blank has a film of a transition metal/silicon base material comprising a transition metal, silicon, oxygen and nitrogen, having an oxygen content of at least 3 atom %, and satisfying the formula: 4×CSi/100−6×CM/100>1 wherein CSi is a silicon content in atom % and CM is a transition metal content in atom %.
