Abstract:
1. A chemical mechanical polishing composition, comprising, as initial components: water; 0.1 to 40 wt % abrasive having an average particle size of 5 to 150 nm; 0.001 to 1 wt % of an adamantyl substance according to formula (II): wherein A is selected from N and P; wherein each R 8 is independently selected from hydrogen, a saturated or unsaturated C 1-15 alkyl group, C 6-15 aryl group, C 6-15 aralkyl group, C 6-15 alkaryl group; and, wherein the anion in formula (II) can be any anion that balances the + charge on the cation in formula (II); 0 to 1 wt % diquaternary substance according to formula (I): wherein each X is independently selected from N and P; wherein R 1 is a saturated or unsaturated C 1 -C 15 alkyl group, a C 6 -C 15 aryl group and a C 6 -C 15 aralkyl group; wherein R 2 , R 3 , R 4 , R 5 , R 6 and R 7 are each independently selected from selected from a hydrogen, a saturated or unsaturated C 1 -C 15 alkyl group, a C 6 -C 15 aryl group, a C 6 -C 15 aralkyl group and a C 6 -C 15 alkaryl group; and, wherein the anion in formula (I) can be any anion or combination of anions that balance the 2+ charge on the cation in formula (I); and, 0 to 1 wt % of a quaternary ammonium compound selected from tetramethyl ammonium hydroxide, tetraethyl ammonium hydroxide, tetrapropyl ammonium hydroxide, tetraisopropyl ammonium hydroxide, tetracyclopropyl ammonium hydroxide, tetrabutyl ammonium hydroxide, tetraisobutyl ammonium hydroxide, tetratertbutyl ammonium hydroxide, tetrasecbutyl ammonium hydroxide, tetracyclobutyl ammonium hydroxide, tetrapentyl ammonium hydroxide, tetracyclopentyl ammonium hydroxide, tetrahexyl ammonium hydroxide, tetracyclohexyl ammonium hydroxide, and mixtures thereof.
