Patent ID: 10367004

Abstract:
A vertical ferroelectric thin film storage transistor and a data write and read method thereof are disclosed. The vertical ferroelectric thin film storage transistor includes a substrate having a first surface, a first conductive structure, a first insulating layer, a second conductive structure, and a second insulating layer sequentially disposed above a first surface of a substrate, and a vertical hole penetrates through the layers in a direction substantially perpendicular to the first surface of the substrate. A channel layer is disposed on a wall surface of the vertical hole and in electrical contact with the first conductive structure and the second conductive structure. An inner dielectric layer is disposed on one side of the channel layer. A ferroelectric layer is disposed on one side of the inner dielectric layer. A gate structure is disposed on one side of the ferroelectric layer. A third conductive structure is disposed above the second insulating layer or in the substrate, and in electrical contact with the third conducting structure and the gate structure.
