Abstract(in English) | To achieve high performance low-temperature (LT) polycrystalline-silicon (poly-Si) thin-film transistors (TFTs), high-k gate dielectric of sputtered HfO_2 was combined with high-quality lateral large-grained poly-Si thin film fabricated by continuous-wave laser lateral crystallization (CLC). The CET obtained from split CV method indicates 11 nm and HfO_2 gate dielectric shows dielectric constant of 15. Field-effect mobility and S.S. of fabricated CLC LT poly-Si TFTs are 160 cm^2/Vs and 200 mV/dec, respectively. Furthermore, drain current of the TFT was about 4 times higher than that of TFT with SiO_2 gate dielectric. This result demonstrates feasibility of high-k CLC LT poly-Si TFTs |
