Abstract
An ultra-fine pattern deposition apparatus can include a base substrate; a photothermal converter disposed on or in the base substrate and configured to convert optical energy into thermal energy; a source part disposed on the photothermal converter; and a light reflector configured to reflect light based on a refractive index difference between the light reflector and the base substrate, and guide a source material emitted from the source part to a target region based on an opening in the light reflector and the photothermal converter being heated with the thermal energy from the photothermal converter, in which the opening in the light reflector includes a laterally recessed lower part and an upper part protruded from the laterally recessed lower part, and the laterally recessed lower part is between the upper part and the base substrate, and the photothermal converter is disposed between base substrate and the source part.
