Abstract

Oxide semiconductors have gradually replaced amorphous and polycrystalline silicon for thin-film transistor (TFT) because of their high mobility and large-area uniformity. Especially, the oxide semiconductors have also achieved the low-cost manufacturing using a solution process. However, because the solution-processed oxide semiconductors require a high thermal energy to form the oxide thin film, the additional solution synthesis and annealing process are needed for low-temperature solution process. Because the conventional solution-processed oxide thin films have low oxidation level and high residual organic concentration at low annealing temperature, we propose the novel solution process that includes the nitric acid additive and the vacuum ambient annealing as an oxidizing agent and a residual organic suction, respectively. Therefore, we have successfully developed the simple oxide solution process and the soluble InZnO TFT with high field-effect mobility of 3.38 cm2/(V s) at 200 C.
