A semiconductor of which a substance such as a semiconductor photocatalyst is uniformly coated on the surface thereof with a graphitic carbon film and a method of fabricating the same are disclosed. According to the inventive method, a graphitic carbon film having a thickness of 1 nm or less is uniformly formed on the surface of the semiconductor by performing hydrothermal synthesis and pyrolysis on glucose, so as to keep the original structure crystallinity of the semiconductor photocatalyst to be a support of the carbon film.
