The influence of surface state effects of a-IGZO TFTs is investigated and modeled by adopting two different structures. The inverted-staggered TFTs with the less surface state effects show both improved sub-threshold swing and stable performances compared to inverted-coplanar TFTs. Based on our result, the inverted-staggered structure is suitable as high-performance a-IGZO TFTs.
