Abstract
Embodiments provide a semiconductor structure and a method for fabricating the same. The semiconductor structure includes: a substrate; bit lines positioned in the substrate, where each of the bit lines includes a conductive body and a dielectric layer, the conductive body includes a body portion and a plurality of contact portions, the body portion extend along a first direction, the contact portions protrude from a side surface of the body portion facing away from a bottom of the substrate, the contact portions are arranged at intervals along the first direction, and the dielectric layer covers side wall surfaces on left and right sides of the body portion along an extension direction; and transistors positioned on top surfaces of the contact portions facing away from the body portion, and extension directions of channels of the transistors are perpendicular to a plane where the substrate is positioned.
