Abstract
A semiconductor structure and a method for forming a semiconductor structure are provided. The semiconductor structure includes: a substrate, multiple active pillars located in the substrate, and multiple word lines. The multiple active pillars are arranged in an array in a first direction and a second direction. The first direction and the second direction are both directions parallel to a top surface of the substrate, and the first direction and the second direction intersect. The multiple word lines are spaced apart in the first direction. Each of the word lines extends in the second direction and continuously surrounds and covers a portion of a side wall of each of the multiple active pillars arranged in the second direction. Any two adjacent word lines are at least partially staggered in a direction perpendicular to the top surface of the substrate.
