  • Patent number: 9466535
    Abstract: A method of forming target patterns is disclosed. A substrate with multiple fins is provided. A plurality of mask patterns is formed across the fins and in at least a part of non-target areas. Target patterns are formed respectively in trenches between the mask patterns.
