Abstract:
1. A method for manufacturing double-sided metallized metal-ceramic substrates in the form of DCB packets, the method comprising the steps of: forming at least one DCB packet, the at least one DCB packet comprising a first metal layer and a second metal layer and a ceramic layer located between the first and the second metal layers and the at least one DCB packet is formed by a bonding method wherein the first and the second metal layer are oxidized on both surface sides, placed on the ceramic layer in a nitrogen atmosphere with an oxygen content of 10×10 bonding the first metal layer to the second metal layer with the ceramic layer by heating to a direct bonding temperature to form the at least one DCB packet while the first metal layer, the second metal layer and the ceramic layer are supported on the separating layer which is on the at least one base plate, wherein the base plate is made of a component selected from mullite, ZrO
