Abstract:
1. A method for removing a copper-compatible resist, comprising combining about 10 to 30% by weight of an alkanol amine solvent, combining about 10 to 80% by weight of a glycol group solvent, combining about 9.5 to 80% by weight of a polar solvent, and combining about 0.5 to 10% by weight of a corrosion inhibitor, wherein the the alkanol amine solvent is selected from at least one of an alkyl group consisting of N-methylethanolamine, N-ethylethanolamine, diethylethanolamine and dimethylethanolamine, and wherein the corrosion inhibitor is selected from an mercapto group consisting of mercaptobenzodiazole, mercaptoethanol, mercaptopropanediol, dimethylthiophenol, propylthiophenol, methoxythiophenol, methylthiophenol, thioanisole, tert-butylthiophenol, tert-buthyl-2-methylthiophenol, mercaptomethylimidazole, and mercaptomethylbenzimidazole.
