ANTI-REFLECTIVE COATINGS FOR PHOTOLITHOGRAPHY AND METHODS OF PREPARATION THEREOF
Abstract:
Anti-reflective coating materials for ultraviolet photolithography include at least one absorbing compound and at least one material modification agent, such as at least one porogen, at least one high-boiling solvent, at least one densifying agent, at least one capping agent, at least one leveling agent, at least one catalyst, at least one replacement solvent, at least one pH tuning agent, and/or a combination thereof that are incorporated into inorganic-based materials or inorganic compositions and/or compounds. Suitable absorbing compounds are those that absorb around wavelengths such as 365 nm, 248 nm, 193 nm and 157 nm that may be used in photolithography.
