Epistar Increases LED Capacity Again with More AIXTRON MOCVD Tools

AACHEN, Germany--()--AIXTRON AG is pleased to announce a third multiple order, received in the fourth quarter 2007 from Epistar, one of the world's leading manufacturers of Ultra-High-Brightness (UHB) LEDs. The latest order again includes both multiple CRIUS(TM) Close Coupled Showerhead(TM) (CCS) reactors as well as AIX 2800G4 HT Planetary Reactor(TM) systems which are AIXTRON's flagship products for large scale GaN-based LED manufacturing.

To be delivered later this year, the high capacity MOCVD reactors are required for Epistar's ongoing expansion of LED production capacity. Together with the multiple order announced in October, 2007, Epistar was the single largest individual system investor in Q4 and continues to set the pace for investment in LED technology.

Dr. Ming-Jiunn Jou, Executive Vice President, Epistar comments: 'Once again Epistar is favoring AIXTRON Group MOCVD process technology and equipment for the next stage in planning for production capacity expansion. Our two companies have worked together for over a decade in perfecting the application of MOCVD to the challenges of manufacturing high volume, cost competitive UHB LEDs. To date these reactors have proven well up to the task thanks to excellent uniformity, efficient precursor utilization and other key features. We are now preparing for the installation and rapid commissioning of the new machines with the help of the customary AIXTRON local support and service to meet market demand.'

Epistar was the launch customer for the AIX 2800G4 HT and CRIUS(TM) systems, the world's highest capacity proven reactors for GaN LED production.

Epistar is a leading manufacturer of UHB LEDs for applications such as cellular phones, automotive lighting, full color screens and displays, traffic signals and indicators for electronic equipment; Epistar's high speed LEDs are also used as lighting sources in the fiber-optics industry.
