    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.

    摘要: A method forming a tungsten contact can include forming a contact hole in an interlayer dielectric layer to expose a portion of an underlying silicon based substrate and to form a side wall of the contact hole. A tungsten silicide layer can be formed on at least on the exposed portion of the substrate. A tungsten nitride layer can be conformally formed on a surface of the interlayer dielectric layer, on the tungsten silicide layer and on the side wall. A contact tungsten layer can be formed on the tungsten nitride layer to fill the contact hole. Related apparatus and contacts are also disclosed.
