  • Use of surfactants having at least three short-chain perfluorinated groups in formulations for photo mask cleaning
    Patent number: 9891520
    Abstract: In a method for cleaning photo masks having patterns with smallest line-space dimensions below 200 nm, a surfactant composition A is used, wherein A contains at least three short-chain perfluorinated groups Rf selected from the group consisting of trifluoromethyl, pentafluoroethyl, 1-heptafluoropropyl, 2-heptafluoropropyl, and pentafluorosulfanyl and wherein A exhibits, at a 1% by weight aqueous solution, a static surface tension below 25 mN/m.
    Type: Grant
