Aqueous cleaning compositions comprising a tertiary organic amine, an organic acid, a non-metallic fluoride salt, a corrosion inhibitor, e.g., ascorbic acid or its derivatives alone or in combination, balance water, effective to remove plasma processing residues (sidewall polymer) which include metal-organic complexes and/or inorganic salts, oxides, hydroxides or complexes which form films or residues either alone or in combination with the organic polymer resins. These compositions clean effectively at low temperatures without etching metal or dielectric layers, including low-κ dielectric materials. |
