Abstract
A method for preparing a semiconductor structure, a semiconductor structure and a semiconductor memory are provided. The method includes: a substrate is provided; a stack structure is formed on the substrate; the stack structure is divided into multiple channel areas, first source-drain areas and second source-drain areas. Each channel area extends in a second direction, each first source-drain area and each second source-drain area extend in a first direction, and the first source-drain area and the second source-drain area are located on the same side of the channel area; a first source-drain structure extending in the first direction is formed in the first source-drain area and a second source-drain structure extending in the first direction is formed in the second source-drain area; and a channel structure extending in the second direction is formed in the channel area.
