  • Semiconductor device and manufacturing process therefor as well as plating solution
    Publication number: 20050196959
    Abstract: A semiconductor device of improved stress-migration resistance and reliability includes an insulating film having formed therein a lower interconnection consisting of a barrier metal film and a copper-silver alloy film, on which is then formed an interlayer insulating film. In the interlayer insulating film is formed an upper interconnection consisting of a barrier metal film and a copper-silver alloy film. The lower and the upper interconnections are made of a copper-silver alloy which contains silver in an amount more than a solid solution limit of silver to copper.
