Ceramic substrate and process for producing same |
摘要 |
A ceramic substrate includes a substrate body formed of ceramic and having a pair of surfaces each assuming a rectangular shape as viewed in plane, and a metallization layer formed on the surface of the substrate body and adapted to braze a metal frame thereon. A composite material layer is disposed between the surface of the substrate body and the metallization layer and is formed such that a ceramic portion, a metal portion 10m formed of a metal similar to a metal component of the metallization layer or a metal which, together with a metal component of the metallization layer, forms an all proportional solid solution, and a glass portion exist together. The thickness of the composite material layer is thinner than that of the metallization layer. A plating layer is deposited on the surface of the metallization layer. |

1. A ceramic substrate comprising
a substrate body formed of ceramic and having a pair of surfaces each assuming a rectangular shape as viewed in plane, and a metallization layer formed on at least one of the surfaces of the substrate body and adapted to mount a metal member thereon, and characterized in that a composite material layer is formed between the surface of the substrate body and the metallization layer and is formed such that a ceramic portion, a metal portion formed of a metal similar to a metal component of the metallization layer or a metal which, together with a metal component of the metallization layer, forms an all proportional solid solution, and a glass portion exist together, a thickness of the composite material layer is thinner than a thickness of the metallization layer, and a plating layer is deposited on a surface of the metallization layer. |
