METAL-ALUMINIUM-NITRIDE ASSEMBLY WITH RARE EARTH NITRIDE PRESENT IN THE INTERFACE TO ENSURE HEAT TRANSFER

摘要

The invention concerns the assembling of a first element comprising aluminium nitride and a second metal or metal alloy element, wherein the interface between the two elements comprises at least a simple or complex rare earth, scandium and/or yttrium nitride. Said assembly can be obtained by soldering providing between the elements a soldering sheet made of an alloy comprising at least a rare earth, scandium and/or yttrium, for example a Cu-Y, Cu-Dy or CU-Ag-Dy alloy.
