We investigated the effects of film thickness (tch) on the radiation hardness of indium-gallium-tin oxide (IGTO) thin films transistors (TFTs). The IGTO TFT with the 12 nm thick channel layer exhibited the best electrical performance and radiation tolerance. The radiation tolerance significantly decreased as tch increased.
