In an example, the 3D memory device includes a memory array structure and a staircase structure. The staircase structure is located in an intermediate of the memory array structure and divides the memory array structure into a first memory array structure and a second memory array structure along a lateral direction. The staircase structure includes a plurality of stairs extending along the lateral direction, and a bridge structure in contact with the memory array structure. The stairs include a stair above one or more dielectric pairs. The stair includes a conductor portion electrically connected to the bridge structure and is electrically connected to the memory array structure through the bridge structure. Along a second lateral direction perpendicular to the lateral direction and away from the bridge structure, a width of the conductor portion decreases."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Staircase structure in three-dimensional memory device and method for forming the same","description":"Embodiments of 3D memory devices having staircase structures and methods for forming the same are disclosed.
