Abstract:
A method of manufacturing a semiconductor device includes forming a wiring metal layer structure; forming a dielectric layer structure arranged directly on the wiring metal layer structure; and forming a bonding pad metal layer structure arranged, at least partially, directly on the dielectric layer structure, wherein a layer thickness of the dielectric layer structure ranges from 1% to 30% of a layer thickness of the wiring metal layer structure, wherein the wiring metal layer structure and the bonding pad metal structure are electrically connected through openings in the dielectric layer structure.
