We present results regarding to extraction of altered localized-states in both amorphous silicon and polycrystalline silicon thin film transistors under various conditions, such as electrical and light stress, crystallization, and hydrogenation. Both deep and tail states have been extracted by fitting calculated current-voltage curves to measured data. The density of deep states as well as tail states in a-Si are significantly increased by stress, which may be the predominant mechanism causing the degradation in a-Si TFT performances. Also, the correlations between trap distributions in poly-Si films and their device performances have been successfully identified by analyzing the effects of crystallization and hydrogenation on the current-voltage characteristics of poly-Si TFT’s.
