Sharp and Semiconductor Energy Laboratory Jointly Develop New Oxide Semiconductor Technology That Will Revolutionize Displays


Sharp and Semiconductor Energy Laboratory have jointly developed a new oxide semiconductor (IGZO) technology with high crystallinity. This new material is expected to be adopted for use in LCD displays for mobile devices such as smartphones where the trend toward higher screen resolutions is growing increasingly strong. Further, it can also be adapted for use in organic EL displays which hold out high expectations for the future. Although challenges to commercialization remain in terms of both service life and production, the two companies will continue to push ahead with R&D in anticipation of future market needs.


Details of this new development will be presented at the 2012 SID Display Week Symposium to be held in Boston, USA, on June 5 as part of the annual international conference of the Society for Information Display.

This jointly developed new IGZO technology imparts crystallinity in an oxide semiconductor composed of indium (In), gallium (Ga) and zinc (Zn). Compared to current amorphous IGZO semiconductors, it enables even smaller thin-film transistors to be achieved and provides higher performance.
