Abstract:
The invention provides a chemical-mechanical polishing composition comprising an abrasive, a self-stopping agent, an aqueous carrier, and optionally, a cationic polymer, and provides a method suitable for polishing a substrate.

Claim (Index 1):
A chemical-mechanical polishing composition comprising:\n (a) an abrasive selected from ceria, zirconia, and combinations thereof, (b) a self-stopping agent selected from a compound of the formula (II): wherein each of X 1 -X 3  is independently selected from N, O, S, a sp 2 -hybridized carbon, and CY 1 Y 2 , wherein each of Y 1  and Y 2  is independently selected from hydrogen, hydroxyl, C 1 -C 6  alkyl, halogen, and combinations thereof, and each of Z 1 -Z 3  is independently selected from hydrogen, hydroxyl, C 1 -C 6  alkyl, and combinations thereof, each of which may be substituted or unsubstituted; a compound of formula (III):\n Z\u2014(C(X 1 X 2 ) n ) p \u2014CO 2 M\u2003\u2003(III), \n wherein Z is selected from N, C 1 -C 6  alkyl, C 1 -C 6  alkenyl, C 1 -C 6  alkynyl, and aryl (e.g., phenyl, benzyl, naphthyl, azulene, anthracene, pyrene, etc.), X 1  and X 2  are independently selected from hydrogen, hydroxy, amino, and C 1 -C 6  alkyl, C 1 -C 6  alkenyl, and wherein X 1  and X 2  taken together with the attached carbon can form a sp 2 -hybridized carbon, n is 1 or 2, p is 0-4, and M is selected from hydrogen and a suitable counterion (e.g., a group I metal), each of which may be substituted or unsubstituted; and combinations thereof; a compound of formula (IV): where X, Y, and Z are independently selected from H, O, S, NH, and CH 2 , R 1 , R 2  and R 3  are independently selected from H, alkyl, alkenyl, alkynyl, aryl, halo, and haloalkyl, and M is selected from hydrogen and a suitable counterion, and\n (c) an aqueous carrier, \n wherein the polishing composition has a pH of about 3 to about 9.
