초록

We report the fabrication of high-performance indium-gallium oxide (IGO) thin-film transistors (TFTs) via plasma-enhanced atomic-layer-deposition (PE-ALD) process with cation composition ratio variation. With accurate control of the composition ratio, IGO(12:3) TFTs showed stable characteristics along with high field-effect mobility (μFET) of 70.69 cm2/Vs. Furthermore by increasing the gallium ratio, IGO(6:3) TFTs showed extremely stable characteristics with threshold voltage (VTH) variations lower than 0.1 V in both positive bias stress (PBS) and negative bias stress (NBS) conditions.
