    Abstract: PROBLEM TO BE SOLVED: To obtain an amorphous perfluorinated polymer for using of a microlithography, the polymer having a higher transmission than 50% in a wavelength of 157nm, and preferably that higher than 55%, and mechanical characteristics suitable for producing a transparent film in the wavelength of the 157 nm. SOLUTION: The perfluorinated polymer does not have an unstable ionic terminal group: COF, COOH, or those amide derivatives, esters, or salts. The polymer is produced from a cyclic unit derived from perfluorodioxole represented by formula (IA) [wherein R' F is equal to R F or OR F (wherein R F is a 1-5C perfluoroalkyl group); and X 1 and X 2 are identical or different, F or CF 3 ]. The polymer optionally contains a unit derived from a perfluorinated comonomer optionally including an oxygen atom. A content of the cyclic unit derived from the perfluorodioxole represented by the formula (IA) is ≥95 mol% in the polymer. COPYRIGHT: (C)2005,JPO&NCIPI
