A lower metal layer and a via in the mixed wired structure is formed in a dielectric structure on the semiconductor substrate, wherein a layer of a barrier metal is absent between the lower metal layer and the via. A trench is formed in the dielectric structure for an upper metal layer that contacts the via. A barrier metal layer is formed on the via and in the trench. The upper metal layer is formed after forming the barrier metal layer, wherein the barrier metal layer is located between the via and the upper metal layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mixed wire structure and method of making the same","description":"A method for connecting metal layers in a mixed wire structure for a semiconductor substrate.
