The device region is defined on a substrate. The active layer is formed by a top portion of the substrate and has a plurality of device cells within the device region and a border structure surrounding the device region. The border structure has at least one branch extending into the device region and is between a portion of the device cells. The STI layer has a first part formed within the border structure to insulate the device cells from one another and a second part surrounding an outer periphery of the border structure. The second part of the STI layer isolates the device cells from a peripheral active region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active region structure and forming method thereof","description":"An active region structure includes a device region, an active layer and a shallow trench isolation (STI) layer.
