Abstract:
A ferroelectric memory device according to an embodiment includes a substrate, an interfacial insulation layer and a ferroelectric insulation layer that are sequentially disposed on an inner wall of a trench formed in the substrate. In addition, the ferroelectric memory device includes a gate electrode layer disposed on the ferroelectric insulation layer. A portion of the ferroelectric insulation layer disposed on the interfacial insulation layer common to a bottom surface of the trench and a portion of the ferroelectric insulation layer disposed on the interfacial insulation layer common to a sidewall surface of the trench have crystal growth planes in directions perpendicular to the bottom surface and the sidewall surface of the trench, respectively.

Claim (Index 12):
A ferroelectric memory device comprising:\n a substrate including a trench formed therein having a bottom surface and a sidewall surface, wherein the bottom surface and the sidewall surface of the trench have a crystal plane of the same family; a ferroelectric insulation layer having the same crystal growth plane on the bottom surface and the sidewall surface of the trench; and a gate electrode layer disposed on the ferroelectric insulation layer, wherein a portion of the ferroelectric insulation layer disposed on the bottom surface of the trench has a remanent polarization orientation aligned in a direction perpendicular to the bottom surface of the trench, and a portion of the ferroelectric insulation layer disposed on the sidewall surface of the trench has a remanent polarization orientation aligned in a direction perpendicular to the sidewall surface of the trench.
