Abstract:
A wiring structure has a silicon layer, a backing layer provided on the silicon layer, the backing layer comprising a copper alloy containing a manganese, and a copper layer provided on the backing layer, and a diffusion barrier layer having an electrical conductivity, the diffusion barrier layer being provided at a region including an interface between the silicon layer and the backing layer, in which a manganese in the diffusion barrier layer is enriched compared with the backing layer.
