The objects of the present invention are to provide a polymer thin film having finer structure than the conventional product, excellent regularity over a wide range and only limited defects, patterned media, methods for producing the thin film and patterned media, and surface modifying agent used in these production methods. n The method of the present invention is for producing a polymer thin film with a plurality of microdomains regularly arranged in a continuous phase by microphase separation on a substrate, comprising steps for forming a grafted silsesquioxane film on the substrate, and for forming a pattern different in chemical properties from the grafted silsesquioxane film in such a way that the pattern corresponds to the microdomain arrangement. |
