  • Preparation of partially cross-linked polymers and their use in pattern formation
    Patent number: 6262181
    Abstract: This invention relates to a process for generating a organically soluble partially cross-linked acid labile polymer according to the present invention comprises the steps of providing a polymer with one or more monomer units, wherein at least one of the monomer units contain one or more pendant COOH or hydroxyl groups; and reacting said polymer with a polyvinyl ether in the presence of a acid catalyst to form links between at least two polymer chains. The resulting polymer can be used as a component in a photoresist formulation.
    Type: Grant
    Filed: December 22, 1999
    Date of Patent: July 17, 2001
    Assignee: Arch Specialty Chemicals, Inc.
