摘要:
In a semiconductor device, an insulating interlayer having a groove is formed on an insulating underlayer. A silicon-diffused metal layer including no metal silicide is buried in the groove. A metal diffusion barrier layer is formed on the silicon-diffused metal layer and the insulating interlayer.
