Abstract
A semiconductor structure, a method for manufacturing a semiconductor structure, and a memory are provided. The semiconductor structure includes: a source and a drain which are arranged in a substrate; a gate dielectric layer arranged in the substrate and covering a sidewall and a bottom portion of a trench defined between the source and the drain; a gate structure arranged in the trench, in which a material of the gate structure includes metal or metal compound; and a gate adjustment layer at least arranged between the gate dielectric layer and the gate structure. A sidewall of the gate structure is provided with a first control area covered with the gate adjustment layer, and a bottom surface of the gate structure is provided with a second control area not covered with the gate adjustment layer. A material of the gate adjustment layer includes polycrystalline silicon.
