摘要: A CMP conditioner having excellent corrosion resistance around abrasive grains includes a grindstone base having, formed on one side, an abrasive grain layer including abrasive grains fixed in a metallic bonding phase treated to form a first protective layer comprising an oxide on the surface of the metallic bonding phase of the abrasive grain layer by the sol-gel method. Subsequently, an aerosol obtained by dispersing fine particles of a brittle material in a gas is jetted and caused to strike on the surface of the first protective layer to form a second protective layer comprising a thick oxide film.
