  • Patent number: 12269983
    Abstract: The inorganic particle according to the present invention is composed of aggregation of crystalline and amorphous small particles and has a spherical and smooth surface. The spherical appearance, low crystallinity and narrow particle size distribution of inorganic particle are more advantageous in reducing scratch defects in the CMP process. In addition, since the small particles on the surface of the inorganic particle provide more active sites, the inorganic particle has an excellent removal rate, so it is advantageous as a next-generation CMP abrasive.
