A device structure is disposed on the substrate. A dielectric layer is disposed on the substrate and covering over the device structure. The dielectric layer has a first air gap above the device structure. The first air gap is enclosed by a dielectric wall constituting as a part of the dielectric layer and the dielectric wall is disposed on the device structure. The dielectric layer has a second air gap, exposing a top of the device structure and adjacent to the dielectric wall."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"A semiconductor device includes a substrate, having a silicon layer on top.
