Abstract
Disclosed are monolithically integrated three-dimensional (3D) DRAM array structures that include one-transistor, one-capacitor (1T1C) cells embedded at multiple device tiers of a layered substrate assembly. In some embodiments, vertical electrically conductive data-line and ground pillars extending through the substrate assembly provide the transistor source and ground voltages, and horizontal electrically conductive access lines at multiple device levels provide the transistor gate voltages. Process flows for fabricating the 3D DRAM arrays are also described.
