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 5):
The polishing composition of  claim 1 , wherein the polishing composition has a pH of 8 to 12.
