Abstract

A semiconductor structure is provided in the present invention, including a substrate with multiple recesses and active areas, multiple bit lines spaced apart in a first direction on the cell region and extending in a second direction perpendicular to the first direction, and the bit line is electrically connected to an active area in the substrate through the recess, and a dummy bit line at an outermost side of the multiple bit lines in the first direction and extending in the second direction, wherein a width of the dummy bit line in the first direction is larger than a width of the bit line in the first direction, and the bit lines and the dummy bit line have the same composition and layer structures.
