Abstract

Embodiments of the present application relate to the field of semiconductor manufacturing technologies, in particular to a semiconductor structure and a mask plate structure. The semiconductor structure includes a substrate, where the substrate is provided therein with active areas and a plurality of bit line structures arranged at intervals in parallel in the substrate. A plurality of word line structures are arranged at intervals in parallel in the substrate. The word line structures and the bit line structures intersect to define a plurality of grids arranged in an array on the substrate. Capacitor plugs are located in the grids. Projection of each of the capacitor plugs on the substrate covers a part of one of the active areas. Cross sections of the capacitor plugs are arcuate in a cross section parallel to a surface of the substrate.
