Aachen/San Jose, August 19th, 2003 – AIXTRON is proud to announce that Lumileds will continue to expand production capacity of its Luxeon products through the execution of a multi-system purchase agreement. The first order has already been placed.

Lumileds, marketing “Light from Silicon Valley”, is a world leading LED manufacturer and can legitimately claim to “provide the world’s brightest, longest lasting LEDs”. With their recent announcement of having the first warm white LED in mass production, Lumileds continues to push LEDs into broader areas of consumption such as incandescent light replacement. AIXTRON is delighted that its equipment has been chosen once more by Lumileds. Lumileds benefits from the strong growth of the LED demand that market researchers are predicting to increase continuously in the years to come. AIXTRON’s ability to provide the highest capacity, lowest cost of ownership MOCVD platform, as evidenced by its continual lead of the MOCVD equipment market, has been a major factor in Lumileds continued satisfaction.

Reflecting on this significant agreement, Dr. Bernd Schulte, Executive VP & COO of Compound Semiconductor Equipment at AIXTRON said, “Recognizing that Lumileds has always been at the forefront of the LED lighting applications, we are even more appreciative that Lumileds is able to sustain its growth and continues to rely on AIXTRON equipment as the basis for its full line of Luxeon products.” Greg Crema, Vice President of Manufacturing of Lumileds further commented, “Through building on our long, successful relationship with AIXTRON, Lumileds has taken an important step in positioning itself to address the unlimited potential for LEDs in the lighting market.”
