More Information
Summary:The inventive concept relates to a block copolymer for lithography, capable of self-assembling and self-healing, and more particularly, to a block copolymer including a first block which is a repeating unit of polymerized siloxane and a second block which is a repeating unit of polymerized alkyl azobenzene acrylate. The alkyl is a linear or branched chain of 1 to 10 carbon atoms, the number (x) of the repeating unit of polymerized siloxane is about 60 to about 80, and the number (y) of the repeating unit of polymerized alkyl azobenzene acrylate is about 15 to about 25. The block copolymer has a cylindrical phase.
