    Abstract: Provided are an electronic device and a method of manufacturing the same. The electronic device includes a ferroelectric crystallization layer between a substrate and a gate electrode and a crystallization prevention layer between the substrate and the ferroelectric crystallization layer. The ferroelectric crystallization layer is at least partially crystallized and includes a dielectric material having ferroelectricity or anti-ferroelectricity. Also, the crystallization prevention layer prevents crystallization in the ferroelectric crystallization layer from being spread toward the substrate.

    Abstract: An electronic device includes: a substrate including a source, a drain, and a channel between the source and the drain; a gate electrode arranged above the substrate and facing the channel, the gate electrode being apart from the channel in a first direction; and a ferroelectric thin film structure between the channel and the gate electrode, the ferroelectric thin film structure including a first ferroelectric layer, a crystallization barrier layer including a dielectric material, and a second ferroelectric layer, which are sequentially arranged from the channel in the first direction. The average of sizes of crystal grains of the first ferroelectric layer may be less than or equal to the average of sizes of crystal grains of the second ferroelectric layer, and owing to small crystal grains, dispersion of performance may be improved.
