Abstract
A semiconductor structure includes: a transistor structure and a capacitor structure that are arranged along a first direction, where the capacitor structure extends along the first direction; and a wordline staircase structure extending along the first direction, where the wordline staircase structure and the transistor structure are disposed along a second direction intersecting with the first direction. A plane perpendicular to the second direction is used as a reference plane. An orthographic projection of the transistor structure on the reference plane is a first projection. An orthographic projection of the capacitor structure on the reference plane is a second projection. An orthographic projection of the wordline staircase structure on the reference plane is a third projection. The third projection covers the first projection, and the third projection partially overlaps the second projection.
