Method of nanoscale patterning based on controlled pinhole formation

A method of making a stamp having a nanoscale pattern, the method comprising:

• mixing predetermined amounts of a first solvent and a second solvent to generate a solvent, the first solvent and the second solvent being immiscible with each other;
• dissolving a solute material in the solvent to generate a coating material, the solute material having solubility that is higher in the first solvent than in the second solvent;
• applying the coating material onto a substrate to form a plurality of pinholes in the coating material;
• applying a replicating material onto the coating material containing the plurality of pinholes to replicate a pattern of a surface of the coating material containing the plurality of pinholes onto a surface of the replicating material;
• and
• delaminating the replicating material from the coating material for using the surface of the delaminated replicating material as the surface of the stamp.
