    摘要： Polymers containing an acetal or ketal linkage and their use in lithographic photoresist compositions, particularly in chemical amplification photoresists, are provided. The polymer is prepared from at least one first olefinic monomer containing an acetal or ketal linkage, the acid-catalyzed cleavage of which renders the polymer soluble in aqueous base; and at least one second olefinic monomer selected from (i) an olefinic monomer containing a pendant fluorinated hydroxyalkyl group RH, (ii) an olefinic monomer containing a pendant fluorinated alkylsulfonamide group RS, and (iii) combinations thereof. The acetal or ketal linkage may be contained within an acid-cleavable substituent RCL in the first olefinic monomer. A method for using the photoresist compositions containing these polymers in preparing a patterned substrate is also provided in which the polymer is rendered soluble in aqueous base at a temperature of less than about 100° C. by acid-catalyzed deprotection of pendent acetal- or ketal-protected carboxylic acid groups.

    摘要： A photoresist composition is provided that includes a polymer having at least one acrylate or methacrylate monomer having a formula where R1 represents hydrogen (H), a linear or branched alkyl group of 1 to 20 carbons, or a semi- or perfluorinated linear or branched alkyl group of 1 to 20 carbons; and where R2 represents an unsubstituted aliphatic group or a substituted aliphatic group having zero or one trifluoromethyl (CF3) group attached to each carbon of the substituted aliphatic group, or a substituted or unsubstituted aromatic group; and where R3 represents hydrogen (H), methyl (CH3), trifluoromethyl (CF3), difluoromethyl(CHF2), fluoromethyl (CH2F), or a semi- or perfluorinated aliphatic chain; and where R4 represents trifluoromethyl (CF3), difluoromethyl (CHF2), fluoromethyl (CH2F), or a semi- or perfluorinated substituted or unsubstituted aliphatic group. A method of patterning a substrate using the photoresist composition is also provided herein.
