摘要:
A metallization, for carrying current in an electrical component, includes a bottom layer overlying a substrate surface and includes titanium (Ti) or a titanium compound as main constituent. An upper layer overlies the bottom layer and includes copper (Cu) as main constituent. The bottom layer and the upper layer form a base layer. A top layer is in direct contact with the upper layer and includes aluminum (Al) as main constituent. The base layer further includes a middle layer, consisting of silver, that is arranged between the bottom layer and the upper layer.
