Abstract (in Japanese) (See Japanese page) 
(in English) A new simulation model for current-voltage characteristics of oxide semiconductor thin-film transistors (a-IGZO TFTs) is presented. This model is developed on the basis of the one-dimensional Poisson equation to significantly reduce the calculation time as compared to a widely-used two-dimensional approach. Furthermore, the model takes into account trap states in the band gap, and also includes both drift and diffusion components of the drain current for precise simulation. The developed model can accurately reproduce the drain current characteristics of a-IGZO TFTs over a wide range of gate and drain voltages, which enables faster and accurate TFT structure design, as well as characteristic analyses.
