METHOD FOR PRODUCING A SINTERED JOINT BETWEEN A CERAMIC SUBSTRATE AND A CARRIER
A method for producing a sintered joint between a ceramic substrate and a carrier is disclosed. The method includes pre-heating the carrier by increasing a temperature of the carrier from an initial temperature to at least a first threshold temperature. A pressure, with which the pre-heated carrier, the ceramic substrate and a powder-including layer disposed between the pre-heated carrier and the ceramic substrate are pressed against one another, is increased from an initial pressure of less than or equal to an initial pressure threshold to at least a first pressure threshold, and the powder-including layer is sintered by simultaneously keeping the pressure for at least a minimum sintering time at at least the first pressure threshold and the temperature of the carrier at at least the first temperature threshold so that the powder-including layer is converted into a joining layer joining the carrier and the ceramic substrate. Thereby, the first temperature threshold is a temperature which allows for sintering the powder-including layer when it is heated to that temperature.
