Kyma's Native GaN Featured at ICNS-7

Raleigh, NC / September 17, 2007 - Kyma Technologies, Inc., a leading supplier of ultra-high purity crystalline gallium nitride (GaN) and aluminum nitride (AlN) materials and related products and services, is pleased to report that their native GaN substrate products will be featured in three scientific papers to be presented at the 7th International Conference of Nitride Semiconductors (ICNS-7), which takes place this week in Las Vegas, Nevada, USA.

 

Kyma has several collaborative research and development partnerships with leading government and academic research groups to help understand and improve their products and to demonstrate the potential of their products in a broad range of nitride semiconductor device applications. The three ICNS-7 papers that feature Kyma's GaN products are the outcome of three of those collaborative partnerships.

The electrical characteristics of Kyma's native c-plane semi-insulating GaN will be the topic of a joint Air Force Research Laboratory (AFRL)-Kyma paper entitled "Electrical Properties and Deep Centers in Semi-Insulating Fe-Doped Native GaN Substrates Grown by Hydride Vapor Phase Epitaxy" and will presented on Monday September 17th by AFRL's Dr. Fang in the poster session subsection on Defects.

The structural characteristics of Kyma's native non-polar GaN will be the topic of a joint North Carolina State University (NCSU)-Kyma paper entitled "Characterization of Low Defect Density Non-Polar Native GaN Substrates" and will be presented on Monday September 17th by K.-Y. (Alvin) Lai of NCSU MSE Professor Mark Johnson's group in the session on Bulk Growth and HVPE II.

The device characteristics of deep green LEDs that utilize Kyma's native c-plane n+ GaN substrates will be the topic of a joint Rensselaer Polytechnic Institute (RPI)-Kyma paper entitled "Improved Performance of GaInN Based Deep Green Light Emitting Diodes through V-Defect Reduction" and will be presented on Wednesday September 19th by Dr. Theeradetch Detchprohm of RPI Constellation Chair Professor Christian Wetzel's group in the session on Solid State Lighting and LEDs.

Dr. Keith Evans, Kyma's President and CEO, commented, "It is often said that it takes a village to raise a child. I believe that it takes a portfolio of strategic partnerships to support the growth of a high technology startup. We are grateful for the energy and scientific voracity of our partners for their efforts in these win-win partnerships."

Dr. Evans and Dr. Drew Hanser, Kyma's Chief Technology Office and Vice President of Business Development, will both be available at ICNS-7 to meet with interested parties.

About Kyma Technologies

Kyma spun out of North Carolina State University's Materials Science and Engineering Department in 1998 to pursue the development of gallium nitride (GaN) and aluminum nitride (AlN) substrates for a broad range of high performance nitride semiconductor device applications. Kyma's substrates have great potential to enable critically needed improvements in device cost, performance, and reliability and thus are expected to replace most foreign substrates such as sapphire and silicon carbide for the most demanding applications.

Kyma's diversified product offering includes: ultra-low defect density native (free-standing) GaN in customer-defined orientation including polar (c-plane Ga-face or N-face) and non-polar (a-plane and m-plane), GaN and AlN templates grown on sapphire and other substrates, and ultra-high purity polycrystalline GaN.

The market for nitride semiconductor devices is expected to surpass $9B by 2010. The combined addressable market for GaN and AlN substrates is expected to surpass $500M by 2010.
