The memory device includes: a substrate, a word line, a bit line, a conductive pillar, a landing pad and a storage capacitor. The substrate has an active region. The word line is formed in the substrate and intersected with the active region. The bit line extends over the substrate and electrically connected to the active region. The conductive pillar is disposed over the substrate and electrically connected to the active region. The conductive pillar and the bit line are located at opposite sides of the word line. The landing pad is disposed on and electrically connected to the conductive pillar. A sidewall of the conductive pillar is laterally recessed from a sidewall of the landing pad. The storage capacitor is disposed over and electrically connected to the landing pad."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory device with air gaps for reducing capacitive coupling","description":"The present application provides a memory device with air gaps for reducing capacitive coupling.
