For next generation devices such as smart phones or tablet computers, high performance thin film transistors are indispensable. InGaZnO (A Compound semiconductor consisting of In, Ga, and Zn: also called IGZO) film is regarded as a promising material for transistor production. Prof. Y.Uraoka and Assoc. Prof. Y.Ishikawa of the Information Device Science Laboratory, Graduate School of Materials Science, Nara Institute of Science and Technology (NAIST, President: N. Ogasawara) succeeded in the fabrication of a high quality gate insulator which greatly enhances the reliability of IGZO TFT's, through collaborative work with Nissin Electric Corporation.

This achievement will be presented at the IEEE/AMFPD International Conference, which will be held from July 2nd to the 5th in Kyoto.
