CMP systems and methods utilizing amine-containing polymers

摘要

The invention provides a chemical-mechanical polishing system and method comprising a liquid carrier, a polishing pad and/or an abrasive, and at least one amine-containing polymer, wherein the amine-containing polymer has about 5 or more sequential atoms separating the nitrogen atoms of the amino functional groups or is a block copolymer with at least one polymer block comprising one or more amine functional groups and at least one polymer block not comprising any amine functional groups.
