Metal-ceramic substrate for electric circuits or modules, method for producing one such substrate and module comprising one such substrate

摘要

The invention relates to a metal-ceramic substrate for electric circuits or modules, said substrate including a ceramic layer which is provided with at least one metallic layer of a first type applied to a surface of said ceramic layer in a plane manner. An insulating layer made up of a glass-containing material is applied to at least one partial region of a surface of the metallic layer of the first type, said surface opposing the ceramic layer, and a metallic layer of a second type is applied to the insulating layer, the insulating layer and the metallic layer of a second type respectively being thinner then the ceramic layer and the metallic layer of the first type.
