摘要：

This paper aims at improving the performances of Titanium-doped Zinc-oxide (TZO) Thin-Film-Transistors (TFTs) by optimizing the source/drain materials. We successfully fabricate TZO TFTs with different source/drain materials, such as AI, Mo, Cr, Mo/Al/Mo and Cr/AIICr. No intentional substrate-heating is performed during each deposition step and the highest process temperature is 80 degrees C. The results show that TFTs adopting Cr/AIICr as source/drain exhibit improved electrical properties with a high saturation mobility (mu(sat)) of 171.4 cm(2)V(-1)S(-1), a low subthreshold swing (SS) of 0.25 Y/decade, a high I-on/I-off ratio of 2x10(8) and a threshold voltage (Vth) of 3.0V.
