    摘要： A novel radiation-sensitive lithographic photoresist composition is provided which has improved sensitivity and resolution. The composition comprises a photosensitive acid generator and an acrylate or methacrylate copolymer. The copolymer contains first monomeric units having polar pendant groups and second monomeric units containing photoacid-cleavable ester groups. The polar pendant groups preferably comprise C.sub.6 -C.sub.12 alicyclic substituents containing a polar moiety R*, wherein the alicyclic substituents are bound through a linker moiety to the polymer backbone. Other monomeric units may be included as well. A process for using the composition to generate resist images on a substrate, i.e., in the manufacture of integrated circuits or the like.

    摘要： An improved photoimagable cationically polymerizable epoxy based coating material is provided, that is suitable for use on a variety of substrates including epoxy-glass laminate boards cured with dicyandiamide. The material includes an epoxy resin system consisting essentially of between about 10% and about 80% by weight of a polyol resin which is a condensation product of epichlorohydrin and bisphenol A having a molecular weight of between about 40,000 and 130,000; and between about 35% and 72% by weight of an epoxidized glycidyl ether of a brominated bisphenol A having a softening point of between about 60° C. and about 110° C. and a molecular weight of between about 600 and 2,500. Optionally, a third resin may be added to the resin system. To this resin system is added about 0.1 to about 15 parts by weight per 100 parts of resin of a cationic photoinitiator capable of initiating polymerization of said epoxidized resin system upon exposure to actinic radiation; the system being further characterized by having an absorbance of light in the 330 to 700 nm region of less than 0.1 for a 2.0 mil thick film. Optionally a photosensitizer such as perylene and its derivatives or anthracene and its derivatives may be added.

    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.
