    摘要: A copper interconnect structure in a semiconductor device including an opening formed in a dielectric layer of the semiconductor device, the opening having sidewalls and a bottom. A first barrier layer is conformally deposited on the sidewalls and the bottom of the opening. A first seed layer is conformally deposited on the first barrier layer. A second barrier layer is conformally deposited on the first seed layer. A second seed layer is conformally deposited on the second barrier layer and a conductive plug is deposited in the opening of the dielectric layer.
