논문 초록 (Abstract)

Amorphous-gallium-indium-zinc-oxide (⁠a -GIZO) thin filmtransistors (TFTs) are fabricated without annealing, using processes and equipment for conventional a-Si:H TFTs. It has been very difficult to obtain sound TFT characteristics, because the a -GIZO active layer becomes conductive after dry etching the Mo source/drain electrode and depositing the a-SiO2 passivation layer. To prevent such damages, N2O plasma is applied to the back surface of the a -GIZO channel layer before a-SiO2 deposition. N2O plasma-treated a -GIZO TFTs exhibit excellent electrical properties: a field effect mobility of 37cm2/Vs ⁠, a threshold voltage of 0.1V ⁠, a subthreshold swing of 0.25V /decade, and an Ion∕off ratio of 7
