Abstract
During this presentation, I would like to introduce the concept our H-series blanks which we have developed in conjunction with our new production line. I'd like to present a comparison between quality of our former blanks and the new HQZ material now offered. Finally, I want to address the effect of defect on the substrate which are not presently detectable using automated inspection equipment after the final manufacturing phase.
