Abstract:
A metal interconnection of semiconductor device and method for fabricating the same is provided. The semiconductor device can include a semiconductor substrate formed with device structures such as transistors. An interlayer dielectric layer can be formed on the semiconductor substrate with a metal interconnection formed therethrough. A spacer can be formed on at least a portion of a sidewall of the metal interconnection. A diffusion barrier can be formed on an upper surface of the metal interconnection.
