The semiconductor device includes a device substrate, having a device structure layer and a buried dielectric layer, wherein the buried dielectric layer is disposed on a semiconductor layer of the device structure layer. A metal layer is disposed on the buried dielectric layer and surrounded by a first inter-layer dielectric (ILD) layer. A region of the metal layer has a plurality of openings. The buried dielectric layer has an air gap under and exposing the region of the metal layer with the openings. A second ILD layer is disposed on the metal layer and sealing the air gap at the openings of the metal layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and method for fabricating semiconductor device","description":"A semiconductor device is provided.
