Abstract
A semiconductor structure, a method for manufacturing a semiconductor structure, and a memory are provided. The semiconductor structure includes a substrate, a plurality of active pillars arranged above the substrate, a storage structure, and a plurality of transistors. The active pillars are arranged in an array in a first direction and in a second direction. Each active pillar includes a first sub active pillar and a second sub active pillar arranged on the first sub active pillar. The first direction and the second direction intersect with each other and are both parallel to a top surface of the substrate. A material of the first sub active pillar includes a first element, and resistivity of the first sub active pillar including the first element is less than resistivity of the first sub active pillar absence of the first element. The storage structure covers a sidewall of the first sub active pillar.
