Abstract

A method of fabricating nanostructure for antireflection and a method of fabricating a photo device integrated with the nanostructure for antireflection are provided. The fabrication of the nanostructure for antireflection includes coating a solution containing a combination of metal ions with organic or inorganic ions on a substrate, sintering the coated solution using an annealing process to grow nanoscale metal particles, and chemically etching the substrate using the metal particles as mask or accelerator to form a subwavelength nanostructure on the surface of the substrate, thereby manufacturing the nanostructure for antireflection without an apparatus requiring a vacuum state using a simple method for a short amount of time to minimize reflection of light at an interface between a semiconductor material and the air, and producing a photo device having good luminous efficiency and performance at low cost in large quantities by applying it to the photo device.
