  • Publication number: 20150228298
    Abstract: The present invention relates to a method for forming a silicon oxide nanopattern, in which the method can be used to easily form a nanodot or nanohole-type nanopattern, and a metal nanopattern formed by using the same can be properly applied to a next-generation magnetic recording medium for storage information, etc., a method for forming a metal nanopattern, and a magnetic recording medium for information storage using the same. The method for forming a silicon oxide nanopattern includes the steps of forming a block copolymer thin film including specific hard segments and soft segments containing a (meth)acrylate-based repeating unit on silicon oxide of a substrate; conducting orientation of the thin film; selectively removing the soft segments from the block copolymer thin film; and conducting reactive ion etching of silicon oxide using the block copolymer thin film from which the soft segments are removed, as a mask to form a silicon oxide nanodot or nanohole pattern.
