The second area is arranged between the first area and the third area. The semiconductor structure includes: a substrate; a shallow trench isolation structure arranged in the substrate and configured to isolate the substrate into a plurality of active areas, in which the active areas in the first area form a semiconductor device; a dielectric layer arranged on the substrate; a through hole structure arranged in the third area and penetrating through the dielectric layer and the substrate; and a stress buffer structure arranged in the second area and including a first buffer doped area, in which the first buffer doped area is arranged in the active areas and formed by doping the active areas with a first buffer impurity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor structure","description":"A semiconductor structure has a first area, a second area and a third area.
