Abstract
The invention relates to a novel process for producing a metal-ceramic substrate in which at least one surface side of the ceramic layer is provided with at least one first structured metal layer and at least one second metal layer is applied to the first by electroless chemical deposition, and in which at least one depression or hole, or a plurality of depressions or holes are formed in the ceramic layer by laser machining to form a scored line.

A process for producing a metal-ceramic substrate, in which at least one surface side of a ceramic layer is provided with at least one first structured metal layer and at least one second metal layer applied to the first structured metal layer by electroless chemical deposition, and in which at least one depression or hole, or a plurality of depressions or holes are formed in the ceramic layer by laser machining to form a scored line, wherein the laser machining is done after the first structured metal layer is produced in an atmosphere containing at least 30% by volume oxygen.
