Abstract

A semiconductor structure includes a base, a conductive pillar at least located in the base, connecting structures and an electrical connection layer. At least one connecting structure is electrically connected to an end of the conductive pillar, the material of the connecting structure is different from that of the conductive pillar, and a total area of an orthographic projection of the connecting structure on the base is less than an area of an orthographic projection of the conductive pillar on the base. The electrical connection layer is electrically connected to an end of the connecting structure distal from the conductive pillar.
