ABSTRACT:
A process is provided where a ceramic metal substrate is produced by attaching metal foils on either side a ceramic layer to form metal layers and for producing a through connection by placing metal in an opening to form a bridge so that the metal layers are electrically connected together by direct bonding, and a metal body is inserted into the opening to almost fill it, while a surface of the metal body is provided with a layer with chemical compound of metal and reactive gas.
