PROBLEM TO BE SOLVED: To provide a block copolymer film with a microphase-separated structure vertically-oriented to the film surface only by the as-cast method without annealing treatment. SOLUTION: The block copolymer film includes a block copolymer having a number-average molecular weight of 500,000-2,500,000. The block copolymer film has a film thickness of 1μm-1,000μm. In the block copolymer film, a microphase-separated structure by the block copolymer has a structure vertically-oriented to the film surface. COPYRIGHT: (C)2010,JPO&INPIT |
