  • Patent number: 7655158
    Abstract: The corrosion inhibitor blend of at least one corrosion inhibitor base (which may be a Mannich reaction product), a solvent selected from the group consisting of C1 acids and ester and salt derivatives thereof, and optionally a surfactant, has been found to be effective as a corrosion inhibitor for metals in acid media, particularly fluids containing halogen acids. The corrosion inhibitor has improved performance over similar or identical corrosion inhibitor compositions where an alcohol such as methanol is used as a solvent. Suitable, non-limiting possibilities for the solvent include, but are not necessarily limited to formic acid, formate salts, methyl formate, ethyl formate, benzyl formate, formate salts of amines, inorganic formate, and mixtures thereof.

    Abstract: The sarcosine compounds used as a corrosion inhibitor according to the present invention include sarcosine and salt compounds thereof. The corrosion inhibitor is used in chemical mechanical polishing compositions or post CMP clean agents, which forms a protective film on the surface of a work piece to prevent the work piece from corrosion in chemical mechanical polishing, and thus common residue defect on the surface of a work piece due to the use of a conventional corrosion inhibitor (e.g. benzotriazole (BTA)) can be improved or the surface of a work piece can be protected from corrosion in post-CMP cleaning.
