Indium oxide thin film was deposited on glass substrate by radio frequency magnetron sputtering at room temperature. The In2O3 film was polycrystalline with a preferred (111) orientation and a grain size of 33 nm was estimated. The bottom-gate staggered thin film transistors (TFTs) were fabricated by standard photolithography, with In2O3 as active channel layers. The In2O3 TFTs exhibit good gate bias controlling characteristic with a field effect mobility of 6.3 cm2/V·s, an on-off current ratio of 3×103, and a threshold voltage of -0.9 V. Device performance and room temperature fabrication technology make In2O3 TFTs promising for display panel applications.
