Electrical-performance and reliability improvement of flexible low-temperature polycrystalline silicon thin-film transistors via post-annealing process

Abstract: We investigated the improvement methods of the electrical characteristics and reliability of flexible low-temperature polycrystalline silicon (LTPS) thin-film transistors (TFTs) by optimizing the annealing process. We investigated the effect of annealing on the device properties via electrical measurement and density-of-state (DOS) analysis. The annealing temperature should be reduced for flexible LTPS TFTs compared to rigid devices because the range of the thermal stability of flexible substrate is narrower t… Show more

“…The advantages offered by LTPO backplanes extend beyond their capacity for minimizing leakage current. They also encompass outstanding current-driven capabilities attributed to the heightened mobility of low-temperature polysilicon (LTPS) thin-film transistors (TFTs) [2]. Oxide TFTs, manufactured at comparatively low temperatures, exhibit notable stability and reliability during operation -a pivotal factor for ensuring prolonged functionality in electronic devices.…”
