Abstract:
1. A method for manufacturing a microstructure, comprising: forming a guide film on a patterning material, an upper surface of the patterning material being hydrophobic, an opening being made in the guide film, an upper surface of the guide film being hydrophilic, a side surface of the opening being hydrophobic; forming a cured film by applying a solution to cover the patterning material and the guide film, separating the solution into a hydrophobic block and a hydrophilic block, and curing the solution, the solution containing an amphiphilic polymer having a hydrophobic portion and a hydrophilic portion, a length of the hydrophobic portion being longer than a length of the hydrophilic portion, the hydrophobic portion being aggregated in the hydrophobic block, the hydrophilic portion being aggregated in the hydrophilic block; forming a mask member by removing the hydrophilic block from the cured film; and performing processing of the patterning material using the mask member as a mask.
