Abstract: A semiconductor device and a method for manufacturing the same are provided. The semiconductor device includes a substrate, a first dielectric layer, and a first metal plug structure, wherein a circuit element is disposed on the substrate. The first dielectric layer is disposed on the circuit element and on the substrate. The first metal plug structure, including a first barrier metal layer and a first metal interconnector, is embedded in the first dielectric layer. The first metal interconnector is in direct contact with the circuit element. The first barrier metal layer is disposed on the first metal interconnector; wherein the first barrier metal layer and the first metal interconnect have different metal materials.
