Latest Patents

William H Heath holds a patent for a top antireflective coating composition with a low refractive index at a radiation wavelength of 193 nm. This innovative composition is characterized by the presence of an aqueous base-soluble polymer that contains aromatic moieties. The refractive index value of this polymer is less than 1.5 with respect to a radiation wavelength of 193 nm. This patent is particularly useful in 193 nm dry lithographic processes. The polymers with an ethylenic backbone, which also have fluorine and sulfonic acid moieties, have been found to be especially effective. These compositions enable top reflection control at 193 nm while providing ease of use due to their solubility in aqueous alkaline developer solutions.
