Abstract: The triphenylsulfonium bromide was synthesized from the original reactant biphenyl sulfoxide with the improvement of the solvent medium. The reaction time was greatly shortened and its yield was boosted. Then the photoacid generator(PAG) triphenylsulfonium tosylate was synthesized by silver salt replacement. Its FT-IR and 1H NMR spectra were tested.

Key words: photoresist, photoacid generator, triphenylsulfonium tosylate
