The local interconnects are stacked over a substrate and extend laterally along a top surface of the substrate. The metal layers are stacked over the local interconnects and extend laterally along the top surface of the substrate. The conductive layers are close-shaped and concentrically arranged, where each of the local interconnects is coupled to a corresponding conductive layer, and each of the conductive layers is coupled to a corresponding metal layer. The semiconductor device also includes insulating layers that are close-shaped, concentrically arranged, and positioned alternately with respect to the conductive layers so that the conductive layers are spaced apart from one another by the insulating layers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Coaxial contacts for 3D logic and memory","description":"A semiconductor device includes a coaxial contact that has conductive layers extending from local interconnects and being coupled to metal layers.
