  • Patent number: 11034861
    Abstract: Polishing compositions that can selectively and preferentially polish certain dielectric films over other dielectric films are provided herein. These polishing compositions include either cationic or anionic abrasives based on the target dielectric film to be removed and preserved. The polishing compositions utilize a novel electrostatic charge based design, where based on the charge of the abrasives and their electrostatic interaction (forces of attraction or repulsion) with the charge on the dielectric film, various material removal rates and polishing selectivities can be achieved.
