| 20090184287 | SARCOSINE COMPOUND USED AS CORROSION INHIBITOR - 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. | 07-23-2009 |
