Abstract(in English) Highly biaxially oriented poly-Si thin films were formed by double-line beam continuous-wave laser lateral crystallization (DLB-CLC). Crystallinities of the poly-Si thin films were (110), (111), and (211) for the laser scan, transverse, and surface directions, respectively. Silicon grains were elongated in the laser scan direction and one-dimensionally very large silicon grains with lengths of more than 100 μm were fabricated. Using these poly-Si thin films, low-temperature poly-Si TFTs were fabricated at low temperature (≪550℃) and a TFT with a high electron field effect mobility of μ_= 560 cm^2V^<-1>s^<-1> in a linear region was realized. Also, electron mobility variation of no more than 10% was obtained at same crystallization region. Leakage current mechanism was investigated by temperature dependence of the TFT characteristics.
