20130183828 | PATTERN FORMATION METHOD AND GUIDE PATTERN MATERIAL - According to one embodiment, a pattern formation method includes forming a pattern on a layer. The layer has a first surface energy and includes a silicon compound. The pattern has a second surface energy different from the first surface energy. The method includes forming a block polymer on the layer and the pattern. The method includes forming a structure selected from a lamellar structure and a cylindrical structure of the block polymer containing polymers arranged by microphase separation. The lamellar structure is oriented perpendicularly to the layer surface. The cylindrical structure is oriented so as to have an axis parallel to a normal line of the layer surface. The second surface energy is not less than a maximum value of surface energies of the polymers or not more than a minimum value of the surface energies of the polymers. | 07-18-2013 |
