    Abstract: The present invention relates to an oxide electronic device and a manufacturing method thereof. The oxide electronic device comprises: an oxide substrate; an oxide thin film including a different type of oxide from the oxide substrate and formed on the oxide substrate; and a ferroelectric material layer formed on the oxide thin film and controlling the conductivity of two-dimensional electron gas (2DEG) generated on the oxide thin film and the oxide substrate. The manufacturing method comprises the following steps: forming the oxide thin film by depositing oxide which is different from the oxide substrate on the oxide substrate; and forming the ferroelectric material layer controlling the conductivity of 2DEG generated on the oxide thin film and the oxide substrate on the oxide thin film. By using the methods, the conductivity of 2DEG generated on the interface between the different types of oxide can be stably controlled through a non-volatile method by the ferroelectric material layer. Therefore, the conductivity of 2DEG can be constantly maintained without external electric energy, and the device does not require a lot of energy to be operated.
