Zusammenfassung:Embodiments of semiconductor chips and fabrication methods thereof are disclosed. In one example, a semiconductor chip includes a main chip region and a protection structure surrounding the main chip region in a plan view. The protection structure includes a dielectric layer and a conductive portion in the dielectric layer. The conductive portion includes a conductive layer and a core having a material different from that of the conductive layer.
