Chemical mechanical polishing compositions and methods relating thereto |
| abstract |
A polishing composition for removing metal by CMP comprises, a metal oxidizer, an oxide inhibitor, a complexing agent, and an engineered copolymer comprising, molecules of a first moiety having hydrophilic functional groups forming bonds with the metal, and molecules of a second moiety having hydrophobic functional groups that engage a polishing pad during CMP for the pad to remove the engineered copolymer from a surface of the metal, which enables removal of the metal by CMP while minimizing removal of the engineering copolymer from recessed circuit interconnects to minimize dishing. |
