High Power Opto Inc. achieved world class red LED on Aixtron AIX 2600G3 system

Date Announced: 31 Jul 2008

Aachen/Germany -- AIXTRON AG today announced that a Taiwanese
customer has reached a new milestone for red high power LEDs using an AIX 2600G3 Planetary Reactor® system, delivered last year.

High Power Opto Inc. (HPO), located in Taichung, has developed the epi structure for its 622nm metal bond chips on AIXTRON AIX 2600G3 MOCVD reactors.

Dr. K.H. Huang, Chairman of HPO comments: “The results are amongst the best in the world. Keys to our success have been the proprietary HPO metal bond (TW Patent 086340) and mask defined texture process, as well as a highly sophisticated epi process, for which
the AIX 2600G3 system is the ultimate platform.

"With this process, we have been able to improve performance of our packaged HPO MR 40-mil dice to the level of 70lm/W @350mA, corresponding to a wallplug efficiency of 25% at a dominant wavelength of 622nm.”
