  • Publication number: 20110008727
    Abstract: The present invention relates to a radiation sensitive photoresist composition. The composition comprises a polymer comprising at least two monomers. The first monomer has an acid cleavable tertiary ester group. The second monomer is an acidic monomer. The acid cleavable ester group of the polymer has a surprisingly low activation energy which results in improved resist images in lithographic processes.

  • Patent number: 7820369
    Abstract: 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.

  • Patent number: 7811499
    Abstract: An approach is presented for designing a polymeric layer for nanometer scale thermo-mechanical storage devices. Cross-linked polyaryletherketone polymers are used as the recording layers in atomic force data storage devices, giving significantly improved performance when compared to previously reported cross-linked and linear polymers. The cross-linking of the polyaryletherketone polymers may be tuned to match thermal and force parameters required in read-write-erase cycles.

  • Patent number: 7759044
    Abstract: A dissolution modification agent suitable for use in a photoresist composition including a polymer, a photoacid generator and casting solvent. The dissolution modification agent is insoluble in aqueous alkaline developer and inhibits dissolution of the polymer in the developer until acid is generated by the photoacid generator being exposed to actinic radiation, whereupon the dissolution modifying agent, at a suitable temperature, becomes soluble in the developer and allows the polymer to dissolve in the developer. The DMAs are glucosides, cholates, citrates and adamantanedicarboxylates protected with acid-labile ethoxyethyl, tetrahydrofuranyl, and angelicalactonyl groups.
