Abstract: A chemical mechanical polishing slurry including chemical solution, and organic and inorganic particles suspended in the chemical solution is disclosed. The organic particles are formed by polymerized monomers with long chains and/or nebular core-shells; such shapes with increased surface areas can enlarge the contact areas between the polished materials and the organic particles. The chemical solution also includes surfactants attached to the surfaces of the organic particles and the inorganic particles, which separates the organic particles from the inorganic particles. The chemical mechanical polishing slurry has the advantages of both the organic particles and inorganic particles so as to reduce the polishing scratches and enhance the polishing efficiency.
