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 2):
The polishing composition of  claim 1 , wherein\n the pH-adjusting agent 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.
