    摘要: Polymers of a fluorinated backbone having recurring units of formula (1) are novel: R1 is H, F, C1-20 alkyl or fluorinated C1-20 alkyl, R2 is F, C1-20 alkyl or fluorinated C1-20 alkyl, and R3 is C6-20 aryl which may have attached thereto a hydroxyl group and/or a hydroxyl group substituted with an OR4 group wherein R4 is an acid labile group. Using such polymers, resist compositions featuring transparency to excimer laser light and alkali solubility are obtained.

    摘要: Polymers comprising recurring units of an acrylic derivative of fluorinated backbone represented by formula (1) are novel. R1, R2 and R3 are independently H, F, C1-20 alkyl or fluorinated C1-20 alkyl, at least one of R1, R2 and R3 contains fluorine, and R4 is an acid labile group. Using such polymers, resist compositions featuring low absorption of F2 excimer laser light are obtained.
