Fluoroalcohol preparation method, fluorinated monomer, polymer, resist composition and patterning process
Abstract:
Fluoroalcohol compounds of formula (4) are prepared by reacting a fluorine compound of formula (1) with reducing agents or organometallic reagents of formulas (2) and (3) wherein R1 is H or a monovalent C1-C20 hydrocarbon group in which any —CH2— moiety may be replaced by —O— or —C(═O)—, R2 is H or a monovalent C1-C6 hydrocarbon group, R3 and R4 are H or a monovalent C1-C8 hydrocarbon group, and M1 is Li, Na, K, Mg, Zn, Al, B, or Si. From the fluoroalcohol compounds, fluorinated monomers can be produced in a simple and economic way, which are useful in producing polymers for the formulation of radiation-sensitive resist compositions.
