摘要:
A metal line of a semiconductor device having a diffusion barrier including CrxBy and a method for forming the same is described. The metal line of a semiconductor device includes an insulation layer formed on a semiconductor substrate. The insulation layer is formed having a metal line forming region. A diffusion barrier including a CrxBy layer is subsequently formed on the surface of the metal line forming region and the insulation layer. A metal line is finally formed to fill the metal line forming region of the insulation layer on the diffusion barrier including a CrxBy layer.
