The novel sulfonium salt is effective for increasing the dissolution contrast between exposed and unexposed areas. Upon exposure, it generates a substituted alkyl or arylsulfonic acid which is a weak acid, minimizing the influence of side reaction and deactivation during PEB step. The sulfonium salt is useful in a chemically amplified positive resist composition which lends itself to fine patterning and features high resolution.

  • Patent number: 5633409
    Abstract: Trifluoromethanesulfonic and p-toluenesulfonic acid bis- or tris(p-tert-butoxyphenyl)sulfonium salts are novel. They are prepared from bis(p-tert-butoxyphenyl)sulfoxide which is also novel. A chemically amplified positive resist composition which contains the sulfonium salt as a photo-acid generator is highly sensitive to deep-UV rays, electron beams and X-rays, can be developed with alkaline aqueous solution to form a pattern, and is thus suitable for use in a fine patterning technique.
