Abstract
Proposed are an anodic aluminum oxide mold capable of manufacturing a molded article having at least a portion with a dimensional range of several tens of μm, and a mold structure including the same. Additionally, proposed are a method of manufacturing a molded article with a dimensional range of several tens of μm using the anodic aluminum oxide mold, and a molded article manufactured thereby.
Claims6
A method of manufacturing a molded article, the method comprising:
- providing an anodic aluminum oxide mold made of an anodic aluminum oxide film, wherein the anodic aluminum oxide film is made by anodizing a metal base material and removing the metal base material;
- providing a support member configured to support the anodic aluminum oxide mold to maintain flatness;
- providing a metal layer between the anodic aluminum oxide mold and the support member, wherein the metal layer comprises a material capable of electroplating;
- providing a photosensitive material that physically contacts the other surface of the anodic aluminum oxide film;
- forming a plurality of openings in the anodic aluminum oxide film, wherein a shape of the openings is determined according to a shape of patterns resulting from patterning of the photosensitive material provided on the anodic aluminum oxide film
- forming a metal filler in each of the openings;
- and
- removing the anodic aluminum oxide mold,
- wherein the anodic aluminum oxide mold is separately manufactured from the metal layer by anodizing the metal base material to form the anodic aluminum oxide film and subsequently removing the metal base material.
