Patent ID: 8394283

Claim:
A manufacturing method of a three-dimensional structure having a hydrophobic external surface, comprising: preparing a metal member having an inner space corresponding to a size of the three-dimensional structure; anodizing the metal member and forming fine holes on an inner surface of the metal member; forming a replica by coating a non-wetting polymer material on the inner surface of the metal member and forming the non-wetting polymer material to be a replication structure corresponding to the fine holes; forming a structure by adhering a structure forming material on an exposed surface of the replication structure in the metal member; and etching and eliminating the metal member to obtain a hydrophobic external surface, wherein an electrolyte solution fills the inner space of the metal member, an electrode is applied to the metal member, and an anode oxide layer having the fine holes is formed, wherein the structure forming material has adhesion to be adhered on a surface contacting the replication structure.
