发明名称 Hard mask patterns of a semiconductor device and a method for forming the same
摘要 In a method for forming hard mask patterns of a semiconductor device first hard mask patterns are formed on a semiconductor substrate. Second hard mask patterns are formed and include first patterns which are substantially perpendicular to the first hard mask patterns and second patterns which are positioned between the first hard mask patterns. Third hard mask patterns are formed between the first patterns.
