Abstract
A semiconductor device includes: a substrate, and a plurality of conductors. A plurality of conductors are configured to form first electrodes of capacitor structures, and are distributed on one side of the substrate in rows and columns. Each of the conductors comprises a columnar body and a plurality of annular bumps. A part of an axial direction of the columnar body is intersected with the substrate. The annular bumps are arranged around the circumference of the columnar body, and a protruding direction of the annular bumps is parallel to the substrate. The plurality of annular bumps are distributed at intervals in the axial direction of the columnar body. Annular bumps of the conductors adjacent in row and column directions are staggered in a direction perpendicular to the substrate.
