Abstract:
A metal line of semiconductor device and a method of forming the same are provided. An interlayer dielectric (ILD) layer is formed on a semiconductor substrate including a lower line. A via hole is formed in the ILD layer, and a diffusion barrier layer is formed on the ILD layer where the via hole is formed. A copper seed layer and a copper plating layer are repeatedly formed and etched until the hole is completely filled.
