Abstract
A semiconductor structure and a method for manufacturing the semiconductor structure are provided. The semiconductor structure includes: a substrate including a first doped region; a first isolation structure located in the first doped region, a depth of the first isolation structure being greater than that of the first doped region; a first gate structure located on the surface of the substrate of the first doped region and spanning the first isolation structure, a projection width of the first gate structure on the substrate being larger than that of the first isolation structure on the substrate; and second gate structures located on the surface of the substrate and at both sides of the first gate structure.
