Abstract: A method for fabricating a 3D structure with hydrophobic surface using a dipping method is provided to simplify a fabricating process at reduced cost with no need of high-priced equipment for an MEMS process. A method for fabricating a 3D structure with hydrophobic surface using a dipping method comprises the following steps of: coating a metal melting material on a structure to prepare a metal-coated base(S1); anode-oxidizing the metal-coated base in order to form minute holes on the external surface of the metal-coated base(S2); coating a non-wetting polymer on the external surface of the metal-coated base so as to form a cathode reproduction structure corresponding to the minute holes of the metal-coated base(S3); covering the external of the cathode reproduction structure with an outer forming material(S4); and removing the metal coating portion(S5).

Abstract: A nano-glass processing method for forming nano-scale of structure is provided to early and conveniently produce complex three-dimensional structure in nano-scale by applying inter-molecular substitution between glass crystal atoms and metal atoms. The method includes the steps of: forming a molecular substitution layer by forming the molecular substitution layer on a glass substrate, which has crystal atom size larger than glass crystal size of the glass substrate and at least one of charge difference; patterning the molecular substitution layer to become symmetric to pattern to be formed on the glass substrate; substituting crystal atoms of the molecular substitution layer by crystal atoms of the glass substrate; removing the patterned molecular substitution layer from the glass substrate, which was caused by the substitution. The molecular substitution layer is made of metal film possible for the molecular substitution with the glass substrate.
