Chemical-mechanical polishing (CMP) slurry containing clay and CeO2 abrasive particles and method of planarizing surfaces
A composition for planarizing or polishing a surface comprising (a) a liquid carrier, and (b) solids comprising about 0.1 to about 10% by weight clay abrasive particles, and about 0.1% to about 50% by weight CeO2 particles, based on the total weight of solids in the composition, said clay and CeO2 a...

| description | A composition for planarizing or polishing a surface comprising (a) a liquid carrier, and (b) solids comprising about 0.1 to about 10% by weight clay abrasive particles, and about 0.1% to about 50% by weight CeO2 particles, based on the total weight of solids in the composition, said clay and CeO2 abrasive particles having a particle size such that at least 90% of the particles (by number), when slurried in water, have a particle size in the range of about 10 nm to about 10 mum. |
