LUMILEDS CONTRACTS FURTHER AIXTRON SYSTEM: NEW AIX 2600G3HT FOR 24X2" WAFERS IS WORLD LARGEST PLATFORM FOR BLUE, GREEN, CYAN AND WHITE LED FABRICATION

Aachen/San José, January 28 th , 2002, - AIXTRON is pleased to announce that LumiLeds, based in San José, California and well known manufacturer of blue, green, cyan, and white high-brightness LEDs, is adding to its AIXTRON MOCVD platform by ordering the new high throughput AIX 2600G3HT MOCVD Planetary Reactor ® providing the worldwide largest capacity for the growth of GaN, InGaN, AlN and other related compounds. LumiLeds has received worldwide recognition for their high efficiency and long life-time LED-based products, used for example for traffic signals to replace conventional bulbs as well as low voltage krypton or halogen light sources.

The new AIX 2600G3HT represents AIXTRON's success to supply to its green-blue-white LED manufacturing customers the cost-breaking high-capacity G3-MOCVD Technology too. Extremely cost-efficient use of starting materials compliment this tool from a cost-of-ownership perspective for the deposition of Nitride-based materials. This equipment, in addition, fulfills the strict requirements of excellent layer uniformities together with high-yield performance to fast ramp-up capacity in a minimum period of time.

As the same reactor is also capable of eight 4"-wafers, this system represents the most elaborate MOCVD tool for production of GaN/AlGaN transistor structures too.

Dr. Holger Juergensen, CEO of AIXTRON: "We are proud to have this unique customer relationship for more than ten years, when AIXTRON technology contributed significantly to the enabling of UHB-LED development and production. Our team appreciates very much to again deliver our leading MOCVD technology to the world largest LED producer."

Adding the ground-breaking Luxeon TM lighting technology recently, LumiLeds has established a new state-of- the-art: highest flux LEDs available around the world, supplying up to 325 lumens of white light or as much as 790 lumens of red light, and a comparable brightness in other colors offers the preferred and unbeatable choice for LCD monitors and notebook computer screens as well as fabrication of extremely small and sleek light sources. These will provide very low electrical power consumption stretching lighting fixtures into new and never foreseen silhouettes and applications.

As the leading supplier of semiconductor epitaxial equipment and with an installed base of well over 600 systems worldwide AIXTRON is represented in over 15 countries. The company provides an extensive service and support network for maintenance as well as upgrading of systems. Due to its high level of customer service worldwide, AIXTRON has been rated once more among the 2001 10 BEST in its category in VLSI Research Inc’s Customer Satisfaction Survey. In addition AIXTRON’s close and reliable partnership with its stakeholders (e.g. customers, suppliers, inventors) is reflected in the inclusion of AIXTRON shares into the Dow Jones Sustainability Index 2001. AIXTRON's many customers include Agere, Alcatel, Anritsu, ATMI, Avalon, AXT, Epson, Honeywell, IQE, ITT, JDS-Uniphase, Kopin, Mitsubishi,Motorola, Nortel, Optospeed, Osram, Procomp, Samsung, Showa Denko, Sumitomo, Thales, UEC, VPEC as well as numerous Japanese corporations. AIXTRON systems have also been installed in many renowned research institutes worldwide, including CNRS, Fraunhofer Institute, ITRI-OES, JPL, Meijo University, Research Center Jülich, RIKEN, Sandia Nat. Lab, University of Tokyo. AIXTRON is very active in advancing MOCVD technology through collaborations and joint R&D projects with major partners worldwide.
