ABSTRACT:
A semiconductor device (7) has gold coatings (1to5) which are applied to metallic or ceramic components (6) of the semiconductor device (7). The gold coatings (1to4) have a multifunctional multilayer metal coating (8) with a minimal gold layer (9). The gold layer has a thickness dGwhere dG≦0.5 μm. Moreover, at least one metallic interlayer (10) is arranged between the gold layer (9) and the metallic or ceramic components (6).
