摘要:
A fluorinated monomer has formula (1) wherein R1 is H, F, methyl or trifluoromethyl, R2 and R3 are H or a monovalent hydrocarbon group, R4 to R6 each are a monovalent fluorinated hydrocarbon group, A is a divalent hydrocarbon group, and k1 is 0, 1 or 2. A polymer derived from the fluorinated monomer may be endowed with appropriate water repellency, water slip, acid lability and hydrolysis and is useful as an additive polymer in formulating a resist composition.
