VERFAHREN ZUR HERSTELLUNG EINES METALL-KERAMIK-SUBSTRATS UND METALL-KERAMIK-SUBSTRAT, HERGESTELLT MIT EINEM SOLCHEN VERFAHREN
The invention relates to a method for producing a metal-ceramic substrate (20), in which at least one first metal layer (20), at least one ceramic element (10), and at least one second metal layer (22) are arranged one above the other in a stacking direction (S), the at least one ceramic element (20) being arranged between the at least one first metal layer (20) and the at least one second metal layer (22) in the stacking direction (S), and the at least one first metal layer (20) differing materially from the at least one second metal layer (22), said method comprising: • - providing the at least one ceramic element (10); • - forming a first interface metallisation (15) on a first side (S1) of the at least one ceramic element (10), the first interface metallisation (15) comprising a first active metal layer (31) and a first wetting metal layer (32), • - forming a second interface metallisation (16) on a second side (S2) of the at least one ceramic element (10), opposite the first side (S1) of the at least one ceramic element (10), the second interface metallisation (16) comprising a second active metal layer (41) and a second wetting metal layer (42), • wherein the first interface metallisation (15) and/or the second interface metallisation (16) is exposed to an energy input (40), preferably using a laser.
