Popis: | In this paper, microwave assisted annealing (MWAA) technique on atmospheric pressure plasma-enhanced chemical vapor deposition (AP-PECVD) fabricated indium-gallium-zinc-oxide thin-film transistors (IGZO TFTs) is investigated for the first time. MWAA with 300W for 100sec treatment on AP-IGZO TFTs have been fabricated successfully and show excellent electrical characteristics including a VTH of −1.23 V, SS of 0.18 V/dec, µFE of 17.4 cm2/V-s, and Ion/Ioff ratio of 8.14 106. Stretched exponential time dependence model is used to analyze the mechanism of AP-IGZO TFTs under PBTI stress. Accordingly, chemisorption model for oxygen adsorption at AP-IGZO backchannel with and without MWAA is proposed to explain the mechanism under PBTI stress. |
