Applied Materials for IGZO displays

October 16, 2013

On October 16th, Applied Materials announced new technology systems for manufacturing IGZO TFT: the AKT-PiVot® 55K DT PVD, Applied AKT-PiVot 25K DT PVD and Applied AKT 55KS PECVD systems.

Applied Materials supply two sizes of IGZO manufacture equipment: One is for Gen 8.5, 2200mmX2500mm mother glass. One is for Gen 6, 1500mmX1850mm mother glass.

Metal oxide TFT, especially IGZO TFT has been researched for many years. Sharp is the first company to mass produce IGZO TFT since 2012. Although Sharp first announced to produce IGZO TFT in April 2011, it took them one year longer than expected to bring it to mass production. LG started mass produce IGZO TFT for their 55” AMOLED TV since early 2013.

I had a chance to meet Applied Materials team: Max, John, Kerry, Ricky, and Amaya recently in their Santa Clara office. I raised the questions of how to improve IGZO’s stability, uniformity and yield. Applied Materials indicated they have solutions for all three issues. Applied indicated they are working closely with four display companies currently.

More analysis and IGZO display roadmap can be found in our Touch and Emerging Display monthly report.
