The guard ring region extends in a first direction, the first direction being a direction in which the one side of the circuit region extends, includes a guard ring line, an element isolation region, a first defect trapping layer, a second defect trapping layer. The first defect trapping layer extends from a boundary location between the circuit region and the element isolation region to a location spaced from a boundary location between the element isolation region and the guard ring line by an offset distance toward the element isolation region in the second direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor storage device","description":"A semiconductor storage device includes a circuit region formed on a semiconductor substrate, and a guard ring region spaced from one side of the circuit region by a predetermined distance.
