Fujitsu Quantum Devices, Limited (FQD) and the Electron Devices
Department of Sumitomo Electric Industries, Limited (SEI-EDD)
consolidated their compound semiconductor device businesses
into a joint venture company, Eudyna Devices Inc. on April 1st,
2004. Since then, Eudyna has overcome many new challenges to
become the most reliable and respected supplier of compound
semiconductor product in the world with the synergy of the both
companys' accumulated technologies and resources on
development, manufacturing and sales.

The compound semiconductor market has been evolving at a
more rapid pace than ever before. The establishment of the
broadband communication network has enabled the technology to
transmit vast quantities of data such as text, voice, screen images,
and video over the Internet in seconds. This new information and
telecommunications technology has resulted in the development
of high-speed mobile communications, subscriber/access lines,
and mobile computing at a very fast pace, one after another. The
use of compound semiconductor products has been a key building
block expanding and establishing the communications infrastructure.

The compound semiconductor market continues to broaden its
application range from information and communications related
devices to sensor/radar devices, lighting devices excelling at
efficiency, and optical storage devices using visible laser diodes.
In addition, there is a very large expectation that the compound
semiconductor technology will provide the type of devices needed
to expand the automotive and consumer electronics markets.

With several decades of experience, Eudyna will continue to
provide superior products both in performance and cost while
being competitive with the most-advanced technology and mass
production techniques in the information and communication fields.
You can look forward to our continued commitment to provide the
best technology for your applications.
