Abstract:
1. A method of disposing a first microstructure and a second microstructure onto a first substrate, the method comprising steps of: a step (A) of preparing the first substrate, wherein: a step (B) of immersing the first substrate into a electrolyte solution; a step (C) of inserting a second electrode into the electrolyte solution; a step (D) of injecting a bubble into the electrolyte solution with temporarily converting the water repellant insulator film to a hydrophilic film by applying a voltage between the first electrode and the second electrode, so as to dispose the bubble onto the first recess, which is water repellant, without disposing the bubble onto the second recess, which has been temporarily converted to hydrophilic by applying the voltage; a step (E) of dispersing the first microstructure comprising a first hydrophilic surface and a first water-repellent surface into the electrolyte solution in a state where the surface of the first substrate is faced upwardly to dispose the first microstructure onto the first recess in a state where the first water-repellent surface is faced downwardly; a step (F) of injecting the bubble into the electrolyte solution to dispose the bubble onto the second recess without applying voltage between the first electrode and the second electrode; and a step (G) of dispersing the second microstructure comprising a second hydrophilic surface and a second water-repellent surface into the electrolyte solution in a state where the surface of the first substrate is faced upwardly to dispose the second microstructure onto the second recess in a state where the second water-repellent surface is faced downwardly.
