摘要： Compositions characterized by the presence of an aqueous base-soluble polymer having aromatic moieties and a refractive index value n of less than 1.5 with respect to a radiation wavelength of 193 nm have been found which are especially useful as top antireflective coatings in 193 nm dry lithographic processes. Polymers with an ethylenic backbone and having fluorine and sulfonic acid moieties have been found to be especially useful. The compositions enable top reflection control at 193 nm while providing ease of use by virtue of their solubility in aqueous alkaline developer solutions.
