Abstract:
1. A method of manufacturing a nano-structure, the method comprising: forming a photoresist pattern on a base substrate including a neutral layer; forming a sacrifice structure including a first sacrifice block and a second sacrifice block on the base substrate having the photoresist pattern, the sacrifice structure being formed from a first thin film including a first block copolymer; removing the first sacrifice block from the sacrifice structure; after removing the first sacrifice block, oxidizing the neutral layer by using the second sacrifice block as a mask to form a chemical pattern; after oxidizing the neutral layer, removing the second sacrifice block and the photoresist pattern from the base substrate having the chemical pattern; and forming a nano-structure on the base substrate having the chemical pattern, after removing the second sacrifice block and the photoresist pattern, the nano-structure being formed from a second thin film including a second block copolymer.
