    摘要: The invention provides a polymer having (a) at least one repeat unit derived from an ethylenically unsaturated compound having at least one fluorine atom covalently attached to an ethylenically unsaturated carbon atom; and (b) at least one repeat unit derived from an ethylenically unsaturated cyclic compound of structure: (I) wherein n is 0, 1, or 2; and R2 to R4 are independently H; C1-C10 alkyl or alkoxy, optionally substituted by halogen or ether oxygens; or C6-C20 aryl. These polymers can be used in making photoresist compositions and coated substrates.

    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.
