Method for manufacturing omniphobic surface using capillary force

A method of manufacturing an omniphobic surface using capillary force, the method comprising:

• a step of forming a resin layer by applying an ultraviolet rays (UV) curable resin on a first substrate;
• a step of forming a pillar-shaped fine pattern on a second substrate;
• a step of bringing the resin layer and the fine pattern into contact with each other by moving the first substrate or the second substrate so that the resin layer and the fine pattern face each other;
• and
• a step of curing the resin by radiating ultraviolet rays while the resin located around a pillar of the fine pattern moves a certain distance along the pillar in a longitudinal direction of the pillar of the fine pattern by capillary force,
• wherein, after the resin is cured by ultraviolet rays, a reentrant structure in which a horizontal cross-section of the pillar of the fine pattern in contact with the resin layer has a larger area than other horizontal cross-sections of the pillar is formed.
