Abstract: The present invention relates to an asymmetric line nanopattern and a manufacturing method thereof. In particular, the asymmetric line nanopattern can be applied to next generation lithography by using an asymmetric lamellar microdomain formed by a block copolymer blend. To form the nanopattern, the present invention provides the method which forms an asymmetric lamellar pattern using a mixture of two or more copolymers. At least one block of a block copolymer forms a secondary bonding with at least another block of another block copolymer.
