Abstract
A semiconductor device includes a bit line structures on a substrate, extending in a first direction, and being spaced apart from each other in a second direction; channels contacting upper surfaces of the bit line structures and being spaced apart from each other in the first and second directions; upper gate structures extending in the second direction and surrounding the channels disposed in the second direction, the upper gate structures being spaced apart in the first direction; and a capacitor structure including first capacitor electrodes respectively on the channels; a dielectric layer on the first capacitor electrodes, the dielectric layer including a ferroelectric material or an anti-ferroelectric material; a second capacitor electrode layer on the dielectric layer; and capacitor plate electrodes on the second capacitor electrode layer, the capacitor plate electrodes each extending in the second direction and being spaced apart from each other in the first direction.
