摘要

在这项工作中，我们系统地研究了氧气处理对氧化铟-钨薄膜晶体管（IWO-TFTs）材料和电气特性的影响。经过 RTO 处理后，IWO-TFT 的电学特性明显改善，阈下摆幅（S.S. ）达到 122.5 mV/decade，Ion/Ioff 约为 4.7×108，并且具有更强的抗应力降解能力。X 射线光电子能谱（XPS）结果显示，在 RTO 处理条件下，空位含量最低，钨-氧化物（W-O）键含量最高。这表明 RTO 处理能更有效地减少氧空位的数量，稳定 IWO 薄膜的键合结构。因此，经过 RTO 处理的 IWO TFT 表现出更高的性能和可靠性。

Effect of Oxygen Treatment on the Electrical Performance and Reliability of IWO Thin-Film Transistors

In this work, we systematically investigated the effect of oxygen treatment on the material and electrical properties of Indium-Tungsten-Oxide thin film transistors (IWO-TFTs) by O ₂ plasma and rapid thermal oxidation (RTO). With RTO treatment, the electrical characteristics of the IWO-TFTs remarkably depicted a subthreshold swing ( S.S. ) of 122.5 mV/decade, an I _on / I _off of around 4.7×10 ⁸ , and more superior immunity stress-induced degradation. According to the X-ray photoelectron spectroscopy (XPS) results under the RTO treatment condition, the lowest vacancy content and the highest Tungsten-Oxide (W-O) bond content were observed. It indicated that the RTO treatment was more effective in reducing the number of oxygen vacancies and stabilizing the bonding structure of IWO films. As a result, the IWO TFTs subjected to RTO treatment exhibited improved performance and enhanced reliability.
