Poly-Si TFT (Thin Film transistor) fabricated below 170°.C using excimer laser crystallization of sputtered Si films was characterized. In particular, a gate insulator with a breakdown field exceeding 8 MV/cm was deposited by using ICP (Inductively Coupled Plasma) CVD (Chemical Vapor Deposition). A buffer layer possessing high thermal conductivity was inserted between the active channel and the plastic substrate, in order to protect the plastic substrate from the thermal energy of the laser and to increase adhesion of Si film on plastic. Using this method, we successfully fabricate TFT with a stable electron field-effect mobility value greater than 14.7 cm 2/Vsec.
