发明名称 Alkanolamine semiconductor process residue removal composition and process
摘要 A two carbon atom linkage alkanolamine compound composition comprises the two carbon atom linkage alkanolamine compound, gallic acid or catechol, and optionally, an aqueous hydroxylamine solution. The balance of the composition is made up of water, preferably high purity deionized water, or another suitable polar solvent. A process for removing photoresist or other residue from a substrate, such as an integrated circuit semiconductor wafer including titanium metallurgy, comprises contacting the substrate with the composition for a time and at a temperature sufficient to remove the photoresist or other residue from the substrate. Use of the two carbon atom linkage alkanolamine compound in the composition and process provides superior residue removal without attacking titanium or other metallurgy, oxide or nitride layers on the substrate.
