Abstract (en)
[origin: WO2022200406A1] The present invention relates to a method for producing a metal-ceramic substrate (1) comprising: - providing a ceramic element (30) and at least one metal layer (10), wherein the ceramic element (30) and the at least one metal layer (10) extend along a main extension plane (HSE), - joining the ceramic element (30) to the at least one metal layer (10) to form a metal-ceramic substrate (1), in particular by means of a direct metal joining method, a hot isostatic pressing method and/or a soldering method. A structuring, preferably for forming an insulation of metal sections (10') and/or a recess, preferably for forming a solder stop is provided in the at least one metal layer (10) by means of a laser method and a chemical method, in particular an etching.
