Abstract
Conductions and vias between different, stacked metallic layers of a semiconductor device may be mechanically damaged by mechanical strain. According to an exemplary embodiment of the present invention, this mechanical strain may be transferred through the layer structure to the substrate by a grid of grounding structures and isolation and passivation layers which are connected by the grounding structures. This may provide for an enhancement of the lifetime of the semiconductor devices.
