  • Patent number: 7476492
    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.

  • Publication number: 20080153034
    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.
