摘要:
Briefly, in one aspect, this invention provides a catalytic method of preparation of primary and secondary hydrofluoroethers, the process comprising reacting a fluorinated precursor material and an alkylating agent in the presence of a Lewis acid catalyst or a mixture comprising Lewis acid and Bronsted acid catalysts.
摘要:
Novel aqueous, acid etch solutions comprising a fluorinated surfactant are provided. The etch solutions are used with a wide variety of substrates, for example, in the etching of silicon oxide-containing substrates.
摘要:
Photoacid generator salts comprising photoactive cationic moieties and segmented, highly fluorinated-hydrocarbon anionic moieties are disclosed which provide high photoacid strength and can be tailored for solubility and polarity. The present invention further relates to photoacid generators as they are used in photoinitiated acid-catalyzed processes for uses such as photoresists for microlithography and photopolymerization.
