A low-temperature process developed for fabrication of high-mobility polycrystalline silicon thin-film transistors (poly-Si TFTs) is discussed. Its main feature is the use of a sputter-deposited Si film followed by laser irradiation and a sputter-deposited gate SiO 2 film. The poly-Si TFTs have a mobility of 350-cm2/V-s. They have been successfully applied to peripheral circuits for large-area liquid-crystal displays (LCDs)
