GT Advanced Technologies Presenting At Strategies In Light Conference

GT Advanced Technologies (NASDAQ: GTAT) will be presenting at the 2013 Strategies in Light Conference, which runs from February 12-14 in Santa Clara, CA. GT’s Dr. David Joyce, who is Sapphire Wafer Task Force co-chair of the SEMI HB-LED Technical Committee, will present an update on the progress being made in establishing standards for the manufacturing of LEDs. Dr. Joyce’s presentation will focus on the role standards play in establishing a collaboratively driven technology roadmap to lower costs and drive further innovation in the manufacturing of LEDs.

GT has played a leadership role working with its industry peers to drive the evolving standards for LED manufacturing. The SEMI HB-LED Standards Committee on Sapphire was created in late 2010 to bring together industry leaders throughout the LED value chain to establish standards related to sapphire substrates. Their initial work resulted in the publication last year of the SEMI HB1 standard for 150 mm sapphire substrate wafers with input from representatives throughout the LED supply chain from North America, Europe and Asia. The HB-LED Wafer Task force is currently developing further refinements to the HB1 standard. Continued development of this standard is important to the ongoing trend of lower costs and quality improvements necessary for the sustained development of the LED industry.
