Application

Diphenyl 4-tertbutylphenylsulfonium nonafluorobutanesulfonate is primarily used as a photoacid generator (PAG) in photolithography for semiconductor fabrication, where it enables high-resolution patterning through acid-catalyzed reactions. Its nonafluorobutanesulfonate counterion enhances solubility in organic solvents, making it compatible with advanced resist formulations. This compound is also employed in UV-curable coatings and microelectronics packaging due to its efficient acid release and thermal stability. Researchers value its consistent performance in chemically amplified resists (CARs) for next-generation lithography techniques.
