An insulating interlayer is formed on the lower structure. The insulating interlayer is partially removed to form at least one via hole and a dummy via hole. An upper portion of the insulating interlayer is partially removed to form a trench connecting the via hole and the dummy via hole. A first metal layer filling the via hole and the dummy via hole is formed. A second metal layer filling the trench is formed on the first metal layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of forming wiring structures including a plurality of metal layers","description":"In a method of forming a wiring structure, a lower structure is formed on a substrate.
