| Abstract |
| We investigated poly(methyl methacrylate) (PMMA) passivation of solution-processed indium zinc oxide (IZO) thin-film transistors (TFTs). PMMA provides solution-processability and good barrier characteristics against environmental elements such as water and oxygen. The PMMA passivation layers protect the IZO active layer of the TFTs without deteriorating their performance during gate bias stress measurements under ambient conditions, and improve their electrical properties by decreasing leakage current. Moreover, the potential to safely manipulate IZO-TFTs after PMMA passivation was proven by realizing a simple n-channel resistive-load inverter. |
