Claim Text:
1. A method of forming a pattern, comprising: forming a thermally crosslinkable molecule layer including a thermally crosslinkable molecule on a substrate, the thermally crosslinkable molecule having a group that attaches to the substrate and a group that chemically binds to another material by heating; forming a photosensitive composition layer including a photosensitive composition on the thermally crosslinkable molecule layer, the photosensitive composition layer having a surface energy which is changed by irradiation with energy rays; chemically binding the thermally crosslinkable molecule to the photosensitive composition by heating; selectively irradiating the photosensitive composition layer with energy rays; forming a block copolymer layer including a block copolymer on the photosensitive composition layer; and forming a microphase-separated structure in the block copolymer layer.
