The effect of hydrogen and oxygen plasmas on the properties of polycrystalline silicon films and thin-film transistors are investigated. The results clearly demonstrate that an oxygen plasma does not passivate grain boundary defects. However, an oxygen plasma treatment at 300 K still improves the electrical properties of thin-film transistors.
