ANTI-REFLECTIVE COATINGS FOR PHOTOLITHOGRAPHY AND METHODS OF PREPARATION THEREOF

摘要

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 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.
