Abstract
Embodiments of present invention provide a semiconductor structure. The semiconductor structure includes a dynamic random-access-memory (DRAM), and the DRAM includes a vertical transistor and a nanosheet transistor, the vertical transistor being stacked on top of the nanosheet transistor, where a bottom source/drain of the vertical transistor is directly above and connected to a gate of the nanosheet transistor through a conductive via. A method of manufacturing the semiconductor structure is also provided.
