摘要:
Noble metal may be used as a non-oxidizing diffusion barrier to prevent diffusion from copper lines. A diffusion barrier may be formed of a noble metal formed over an adhesion promoting layer or by a noble metal cap over an oxidizable diffusion barrier. The copper lines may also be covered with a noble metal.
