    摘要: A device including a ceramic substrate having a first side and an opposite second side. A first brazing layer is arranged on the first side in regions and a first copper layer is arranged on the first brazing layer. A second brazing layer is arranged on the second side and a second copper layer is arranged on the second brazing layer. The first copper layer has first trenches which extend from a surface of the first copper layer to the first side. The second copper layer has second trenches which extend from a surface of the second copper layer to at least one surface of the second brazing layer. The second copper layer can be conductively connected to a heat sink. The first trenches have first trench bottoms and the second trenches have second trench bottoms, wherein the first trench bottoms are wider than the second trench bottoms.
