Epistar Increases LED Capacity Again with More AIXTRON MOCVD Tools

AACHEN, Germany--(Business Wire)--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.
