Latest Patents

Doug Holmes holds a patent titled "Thermally curable middle layer comprising polyhedral oligomeric silsesquioxanes for 193-nm trilayer resist process." This patent introduces new lithographic compositions designed for use as middle layers in trilayer processes. The compositions consist of an organo-silicon polymer that is either dispersed or dissolved in a solvent system, along with a crosslinking agent and a catalyst. In an alternative embodiment, the organo-silicon polymer can be substituted with a polyhedral oligomeric silsesquioxane-containing polymer or a polyhedral oligomeric silsesquioxane. The inclusion of —OH groups is crucial for the proper cross-linking of the composition. These innovative compositions can be applied as very thin films, ensuring that the underlying bottom anti-reflective coating is protected while maintaining a thin overall stack.
