摘要:
Methods of forming a metal interconnection structure are provided. The methods include forming an insulating layer on a semiconductor substrate including a first metal interconnection. The insulating layer is patterned to form an opening that exposes the first metal interconnection. A first diffusion barrier layer is formed on the exposed first metal interconnection. After forming the first diffusion barrier layer, a second diffusion barrier layer is formed on the first diffusion barrier layer in the opening, the second diffusion barrier layer contacting a sidewall of the opening. A second metal interconnection is formed on the second diffusion barrier layer.
