Abstract:
Chemical mechanical polishing (CMP) compositions, methods and systems are for polishing patterned semiconductor wafers. The CMP compositions comprising an abrasive and a water soluble aluminum compound additive with a pH>7 suppress CMP stop layer (a silicon containing layer, such as silicon nitride, silicon oxide, or silicon carbide) removal rate. CMP compositions optionally contain surfactant to help wet surface; a corrosion inhibitor to provide corrosion inhibition on metal lines, vias, or trenches; and a pH adjusting agent that is used to adjust pH of the CMP polishing composition.

Claim (Index 8):
The method of  claim 7 , wherein\n the pH-adjusting agent in the polishing composition is selected from the group consisting of hydrochloric acid, nitric acid, sulfuric acid, chloroacetic acid, tartaric acid, succinic acid, citric acid, malic acid, malonic acid, sulfonic acid, phosphoric acid, fatty acid, polycarboxylic acid, hydrogen chloride, and mixtures thereof; or is selected from the group consisting of potassium hydroxide, sodium hydroxide, ammonia, quaternary organic ammonium hydroxide (e.g. tetramethylammonium hydroxide), ethylenediamine, piperazine, polyethyleneimine, modified polyethyleneimine, and mixtures thereof; the corrosion inhibitor in the polishing composition is selected from the group consisting of benzotriazole (BTA) and benzotriazole derivatives, triazole and their relative derivatives; imidizole and its derivatives, pyrazole and its derivatives, benzoimidizaole and its derivatives, and combinations thereof; the non-ionic surface wetting agent is selected from the group consisting of ethoxylated alcohol, ethoxylated acetylenic diol surfactant, polyethylene glycol alkyl ether, proplylene glycol alkyl ether, glucoside alkyl ether, polyethylene glycol octylphenyl ether, polyethylene glycol alkylpgenyl ether, glycerol alkyl ester, polyoxyethylene glycol sorbiton alkyl ester, sorbiton alkyl ester, cocamide monoethanol amine, cocamide diethanol amine, dodecyl dimethylamine oxide, block copolymers of polyethylene glycol and polypropylene glycol, polyethoxylated tallow amines, fluorosurfactant, and combinations thereof; the anionic surface wetting agent is selected from the group consisting of alkyl carboxylate, alkyl polyacrylic salt, alkyl sulfate, alkyl phosphate, alkyl bicarboxylate, alkyl bisulfate, alkyl biphosphate, alkoxy carboxylate, alkoxy sulfate, alkoxy phosphate, alkoxy bicarboxylate, alkoxy bisulfate, alkoxy biphosphate, substituted aryl carboxylate, substituted aryl sulfate, substituted aryl phosphate, substituted aryl bicarboxylate, substituted aryl bisulfate, substituted aryl biphosphate, and combinations thereof; the cationic surface wetting agent is a halide of molecules comprising hydrophobic chain and cationic charge center selected from the group consisting of amine, quaternary ammonium, benzyalkonium and alkylpyridinium ion; and the ampholytic surface wetting agent possess both positive (cationic) and negative (anionic) charges on the main molecular chains and with their relative counter ions.
