Abstract:
1. A method for fabricating a structure holding a microstructure, the method comprising the steps of: a) supplying a fluid containing a microstructure having a cylindrical shape in at least one anisotropic groove provided on a substrate; and b) evaporating the fluid so that the microstructure is arranged so as to extend in a longitudinal direction of said at least one anisotropic groove, the method further comprising, before the step a), the step c) of forming said at least one anisotropic groove, and after the step c) and before the step a), the step d) of increasing an affinity with respect to the fluid in a surface of said at least one anisotropic groove to a higher level than an affinity in a surface of the substrate excluding part of the substrate in which said at least one anisotropic groove is formed, wherein: in the step d), the affinity with respect to the fluid is increased in the surface of said at least one anisotropic groove to a higher level than the affinity in the surface of the substrate excluding part of the substrate in which said at least one anisotropic groove is formed by covering, with a first coating film, the part of the substrate in which said at least one anisotropic groove is formed and covering, with a second coating film, the part of the substrate excluding the part of the substrate in which said at least one anisotropic groove is formed, in the step c), said at least one anisotropic groove is formed by etching the substrate using a hydrophobic film formed on the substrate as a mask, the hydrophobic film being used as the second coating film, and in the step d), a hydrophilic film used as the first coating film is formed on the surface of said at least one anisotropic groove.
