    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.

    摘要： A ceramic base plate is divided into a plurality of substrate regions 2 each having corner part 8. A dividing groove 7 is formed between the substrate regions 2 adjacent with each other. The corner part 8 of each of the substrate regions 2 faces a spacing 9B communicated with the dividing groove 7. At least a part of the corner part 8 is arc-shaped. The arc-shaped part of the corner part is tangent to a center line 7a of the dividing groove 7 at a cross point “P” of the spacing 9B with the dividing groove 7. The ceramic base plate is broken along the dividing groove 7 to produce ceramic substrates.
