摘要: In the present invention, a ceramic vacuum chuck 2 having an upper surface for adsorbing a substrate is formed from a colored ceramic sintered body comprising 55-75% by weight alumina (Al2O3), at least 3% by weight Si in terms of oxide (SiO2), at least 0.4% by weight Ca in terms of oxide (CaO), at least 0.4% by weight Mg in terms of oxide (MgO), coloring agent, and 1% or less of impurities. A plurality of pins 4 for supporting the substrate, and a rim 6 are formed on the upper surface by shot blasting using abrasive grains, and the whole of the upper surface is shot peened using spherical particles.
