Abstract
New fabrication method using "Laser Ablation" was first applied to make SMA (TiNi alloy) thin film. TiNi thin film was obtained successfully and it showed one of the highest transformation temperature (351[k]) as SMA thin films. This transformation temperature was as high as conventional bulk TiNi alloy. Effectiveness and superiority to conventional process such as sputtering and vacuum vapor deposition was verified by several experiments in material science. It is considered that the most of advantages of the laser ablation of the TiNi thin film was caused by "ablation effect" in lower temperature rather than "thermal effect" during the process.Keywords
