摘要：
A bonding pad on a substrate has a first metal structure establishing an electrical connection between a device and a bonding area, and a second metal structure arranged at the bonding area. The first metal structure extends, within the bonding area, at least over part of the bonding area between the substrate and the second metal structure, so as to contact the second metal structure, the second metal structure being harder than the first metal structure.
