Three-dimensional plurality of n horizontal memory cells with enhanced high performance circuit density

Abstract

Aspects of the present disclosure provide a semiconductor structure, which can include a lower transistor including a lower channel that is elongated horizontally and includes a lower doped first-type semiconductor layer of a lower doped semiconductor layer, an upper transistor vertically stacked over the lower transistor and including an upper channel that is elongated horizontally and includes an upper doped first-type semiconductor layer of an upper doped semiconductor layer, a lower capacitor electrically connected to and horizontally elongated from the lower transistor and including a first lower plate that includes a lower doped second-type semiconductor layer of the lower doped semiconductor layer, and an upper capacitor vertically stacked over the lower capacitor and electrically connected to and horizontally elongated from the upper transistor and including a first upper plate that includes an upper doped second-type semiconductor layer of the upper doped semiconductor layer.
