Abstract: In a method of manufacturing a semiconductor device, an insulating interlayer is formed on a substrate. The insulating interlayer is partially removed to form an opening. A barrier conductive layer is formed on a sidewall and a bottom of the opening. An RF sputtering process and a DC sputtering process are performed independently on the barrier conductive layer to form a seed layer. A plated layer is formed on the seed layer.
