  • Patent number: 9982166
    Abstract: CMP processes, tools and slurries utilize metal oxide-polymer composite particles that include metal oxide particles and a polymer core. The metal oxide particles are modified with a modifying agent and are partially or fully embedded within the polymer core. Using these processes, tools and slurries can enhance removal rates, reduce defectivity and increase cleanability with respect to comparable systems and substrates.
