Abstract
A semiconductor structure and a manufacturing method therefor are provided. The semiconductor structure includes: a substrate; a plurality of connection pads disposed on a surface of the substrate; and a plurality of electrode pillars, disposed on the substrate and connected to the plurality of connection pads in a one-to-one correspondence. Each electrode pillar includes a first conductor layer and a second conductor layer that are alternately distributed in a direction perpendicular to the substrate. A material of the first conductor layer is different from a material of the second conductor layer. A side surface of the first conductor layer is recessed inward relative to a side surface of the second conductor layer.
