    摘要: A barrier layer and a fabrication thereof are disclosed. The barrier layer comprises at least one barrier material selected from the group consisting of Ta, W, Ti, Ru, Zr, Hf, V, Nb, Cr and Mo and at least one component of oxygen, nitrogen or carbon. A ratio of the component to the barrier material is not less than about 0.45. The fabrication method of the barrier layer applies a working pressure for forming the barrier layer from about 0.5 mTorr to about 200 mTorr substantially without forming crystalline material therein.
