    摘要: The invention relates to a photoresist composition having a protecting group and a protected material incorporated in a cyclic chemical structure. In this invention a protected material has a cyclic ether group or cyclic ester group as a protecting group. A specific example of a cyclic ether group is an alkylene oxide, such as an oxetane group, substituted with one or more fluorinated alkyl groups. A specific example of a cyclic ester is a lactone which may be substituted with methyl groups. The photoresist composition further includes a photoactive component. The photoresist composition of this invention has a high transparency to ultraviolet radiation, particularly at short wavelengths such as 193 nm and 157 nm.

    摘要: There is disclosed a composition comprising a mixture of endo- and exo-2-(bicyclo[2.2.1]hept-5-en-2-yl)-2,2-fluoroalkyl-ethan-2-ol which is rich in the exo isomer, preferably the endo/exo concentration ratio is no greater than 5/95. The composition is useful for forming a repeat unit of a polymer which polymer may further comprise additional repeat units derived from tert-butyl acrylate, hydroxyadamantyl acrylate, protected or unprotected fluorinated olefins, 2-methyl-2-adamantyl acrylate, 2-propenoic acid, 2-hydroxy-1,1,2-trimethylpropyl ester. Polymers of this invention are useful as the binder component of a photoresist composition for microlithography.
