摘要:
A method of fabricating a semiconductor device is provided. The method includes providing a semiconductor substrate having a conductive pattern and forming an insulating layer on the conductive pattern and the semiconductor substrate. The insulating layer is patterned to form an opening which exposes a portion of the conductive pattern. A preliminary diffusion barrier layer is formed on an inner wall of the opening and a top surface of the insulating layer. Oxygen atoms are supplied onto the preliminary diffusion barrier layer to form a first diffusion barrier layer. A metal layer is formed on the first diffusion barrier layer. The metal layer is formed to fill the opening surrounded by the first diffusion barrier layer. A semiconductor device fabricated by the method and a semiconductor cluster tool used in fabrication of the semiconductor device are also provided.
