Patent ID: 8853691

Claim:
A transistor comprising: a first gate; a second gate disposed on one side of the first gate; a first semiconductor layer disposed between the first gate and the second gate; a second semiconductor layer disposed between the first semiconductor layer and the second gate; an oxide layer disposed between the first semiconductor layer and the second semiconductor layer; a first insulation layer disposed between the first gate and the first semiconductor layer; a second insulation layer disposed between the second gate and the second semiconductor layer; a source disposed between the first insulation layer and the second insulation layer; and a drain disposed between the first insulation layer and the second insulation layer, the source and the drain being respectively disposed on two opposite sides of the oxide layer, wherein a material of the first semiconductor layer and the second semiconductor layer is a metal oxide semiconductor material, wherein oxygen concentration of the oxide layer is greater than oxygen concentration of the first semiconductor layer, wherein the oxide layer is in contact with the first semiconductor layer, so as to form a repair interface between the oxide layer and the first semiconductor layer due to diffusion of oxygen, and thus replenishing lost oxygen in the first semiconductor layer and maintaining the oxygen concentration of the first semiconductor layer.
