  • Patent number: 7528098
    Abstract: A residue remover for removing polymeric material and etch residue includes 2-(2-aminoethylamino)-ethanol and optionally another two-carbon atom linkage alkanolamine compound, gallic acid or catechol, water, a polar organic solvent, and hydroxylamine. A process for removing photoresist or other residue from a substrate, such as an integrated circuit semiconductor wafer including titanium metallurgy, includes the steps of contacting the substrate with the above composition for a time and at a temperature sufficient to remove the photoresist or other residue from the substrate. Use of 2-(2-aminoethylamino)-ethanol in the composition and process provides superior residue removal without attacking titanium or other metallurgy on the substrate. The composition preferably has a flash point greater than about 130° C.
    Type: Grant
    Filed: November 24, 2004
    Date of Patent: May 5, 2009
    Assignee: EKC Technology, Inc.
