An organic bottom antireflective composition containing an aromatic polymer compound, a thermal cross-linking agent, and an organic solvent is provided. The aromatic polymer compound has a functional group that absorbs exposure light of a short wavelength of less than about 248 nm and is thermally cross-linkable and de-crosslinkable by acid hydrolysis. The thermal cross-linking agent causes a thermal cross-linking reaction by reacting with the functional group of the aromatic polymer compound. The organic bottom antireflective composition is soluble in a photoresist developer. When the organic bottom antireflective composition is-applied to a photolithography and etching process, a layer formed of the organic bottom antireflective composition can be developed together with a photoresist layer into a pattern in a development process following photoresist exposure and baking processes. As a result, the photolithography and etching process can be simplified, the initial thickness of deposition of the photoresist layer can be reduced, and a processing margin in etching increases.
