Abstract
A mold for processing an optical film includes a substrate defining a microstructure on an outer surface thereof for printing a pattern on the optical film, an aluminum oxide film, and a hydrophobic fluorinated self-assembled monolayer film. The aluminum oxide film is formed on an outer surface of the substrate by atomic layer deposition. The hydrophobic fluorinated self-assembled monolayer film is formed on an outer surface of the aluminum oxide film. The mold provides easy release of the hydrophobic fluorinated self-assembled monolayer film and protection for the mold from abrasion.

A method for manufacturing a mold for processing an optical film, comprising:
- providing a substrate defining a microstructure on an outer surface thereof for printing a pattern on the optical film;
- performing an atomic layer deposition process to form an aluminum oxide film on the outer surface of the substrate;
- and
- dehydrating the aluminum oxide film with a fluorinated fatty acid to form a fluorinated self-assembled monolayer film on an outer surface of the aluminum oxide film.
A mold for processing an optical film comprising:
- a substrate defining a microstructure on an outer surface thereof for printing a pattern on the optical film, an aluminum oxide film formed on an outer surface of the substrate, and a fluorinated self-assembled monolayer film formed on an outer surface of the aluminum oxide film, wherein the fluorinated self-assembled monolayer film is formed by dehydration with the aluminum oxide film and the fluorinated fatty acid.
