Abstract: Disclosed herein are a multi-level device which has a ternary characteristic and can reduce hysteresis, and a method of manufacturing the same. The multi-level device can have a plurality of turn-on voltages, that is, a plurality of threshold voltages, thereby providing multi-level conductivity as a ternary device characteristic. In addition, a double insulating layer made of a dielectric layer and an organic polymer layer is used as a separation layer for channel layer separation, and by removing the hysteresis due to a trap charge at an interface between a channel layer and an insulating layer, a uniform ternary characteristic can always be maintained, and by forming the channel layer on an organic polymer layer, the channel layer can be more stably formed on the insulating layer.
