    摘要: An object of the present invention is to provide a ceramic chuck for mounting a wafer so that the number of particles adhered onto the wafer after chucking can be reduced while maintaining a desired Young's Modulus of the chuck. A ceramic chuck 1 has a surface layer 2 contacting a wafer “W” and a substrate portion 6. The surface layer 2 and substrate portion 6 are produced by co-sintering and the surface layer 2 has a porosity of 1% or higher and 10% or lower and larger than that of the substrate portion 6.

    摘要: A novel method is provided for joining substrates made of aluminum nitride series ceramics to each other, which can perform the joining substantially without leaving an intervening third phase other than aluminum nitride series ceramics at the joining interface of the substrates. The method is performed, for example, by providing a joining agent 3 containing at least an aluminum nitride series ceramics and a flux between the substrates 1 and 2, heat treating the joining agent to eutectically melt the aluminum nitride series ceramics and the flux, then precipitating a reprecipitated phase of the aluminum nitride series ceramics at the joining interface of the substrates. Alternatively, the method is performed by providing a joining agent 3 containing at least an aluminum nitride series ceramics and a flux between the substrates 1 and 2, heating the joining agent to a temperature range T1 which is higher than the melting point of the flux, subsequently heating the joining agent to a temperature range T2 which is higher than the temperature range T1 to exit the components of the flux from the joining interface, ten precipitating the reprecipitated phase of the aluminum nitride series ceramics at the joining interface.
