Abstract
Measures are provided for improving and simplifying metallic bonding processes which enable a reliable initiation of the bonding process and thus contribute to a uniform bonding. The present method provides a further option for using bonding layers. The method in the case of which the two semiconductor elements are bonded to one another via a bond of at least one metallic starting layer and at least one further starting layer provides that the two starting layers are structured in such a way that the layer areas which are assigned to one another have differently sized areal extents. Moreover, the layer thicknesses of the two starting layers should be selected in such a way that the layer areas which are assigned to one another meet the material ratio necessary for the bonding process.
