    摘要: An aqueous polishing agent, comprising, as the abrasive, at least one kind of polymer particles (A) finely dispersed in the aqueous phase and having at their surface a plurality of at least one kind of functional groups (a1 ) capable of interacting with the metals and/or the metal oxides on top of the surfaces to be polished and forming complexes with the said metals and metal cations, the said polymer particles (A) being preparable by the emulsion or suspension polymerization of at least one monomer containing at least one radically polymerizable double bond in the presence of at least one oligomer or polymer containing a plurality of functional groups (a1 ); graft copolymers preparable by the emulsion or suspension polymerization of at least one monomer containing at least one radically polymerizable double bond in the presence of at least one oligomeric or polymeric aminotriazine-polyamine condensate; and a process for the chemical and mechanical polishing of patterned and unstructured metal surfaces making use of the said aqueous polishing agent.

    摘要: An aqueous polishing composition comprising (A) abrasive particles and (B) an amphiphilic nonionic surfactant selected from the group consisting of water-soluble or water-dispersible surfactants having (b1) hydrophobic groups selected from the group consisting of branched alkyl groups having 10 to 18 carbon atoms; and (b2) hydrophilic groups selected from the group consisting of polyoxyalkylene groups comprising (b21) oxyethylene monomer units and (b22) substituted oxyalkylene monomer units wherein the substituents are selected from the group consisting of alkyl, cycloalkyl, or aryl, alkyl-cycloalkyl, alkyl-aryl, cycloalkyl-aryl and alkyl-cycloalkyl-aryl groups, the said polyoxyalkylene group containing the monomer units (b21) and (b22) in random, alternating, gradient and/or blocklike distribution; a CMP process for substrates having patterned or unpatterned low-k or ultra-low-k dielectric layers making use of the said aqueous polishing composition; and the use of the said aqueous polishing composition for manufacturing electrical, mechanical and optical devices.
