摘要: Polycrystalline silicon thin-film transistors (Poly-Si TFTs) with F-ions-implantation were investigated in this study. The electrical characteristics and reliability of the F-ions-implanted poly-Si TFTs were reported for solid phase crystallization (SPC) and excimer laser crystallization (ELC) methods respectively. The thermal annealing causes F-ions to pile up at the poly-Si interface, without the initial pad oxide deposition. With the introduction of fluorine in poly-Si film, the trap state density was effectively reduced. Also, the presence of strong Si-F bonds enhances electrical endurance against hot carrier impact by using F-ions-implantation. These improvements in electrical characteristics are even obvious for the ELC poly-Si TFTs compared to the SPC ones.
