September 29, 2004...At the Sept. 17th Nichia
LED seminar in New York City, attendees found a little blue book in their
gift bag, along with LED samples, an LED flashlight and other giveaways and
handouts. The book, titled "Blue Light Emitting Diode," was
authored by Toshio Ito of Themis Co. Ltd. and carried the subtitle "Invented
by Nichia Corporation and Its Young Engineers." Only 165 pages in length,
well-written and fairly non-technical, a copy of the little book found its way
to me and was a very quick and interesting read. The only glaring technical
flaw was calling GaAs "Gallium Arsenic" when the community knows it's
"Gallium Arsenide." The author definitely got "MOCVD" right.
Evidently just off the press, with an August 2004 print date, it essentially
tells Nichia's side of the story about "the invention" or "the
discovery" of bright, long-lasting GaN based blue spectrum LEDs and laser
diodes. The book is obviously a public rebuttal of the now precedent-setting
and controversial lower court decision in Tokyo awarding Shuji Nakamura 20 billion
Japanese yen (appx. $188 million USA. Ref: our Jan.
30, 2004 coverage). The ruling has since gone to appeal to an upper
court in Japan. For those wanting to get hold of a copy, we've found the link
to purchase the Japanese version of the book. (Go to Themis' second page of book listings). We're still looking for an online
acces to obtain the English translation version, which does exist, and which our editorial
staff has read in its entirety. Content continues for LIGHTimes SecondPage members...

Crystal IS Scores $5 Million Venture FundingSeptember 28, 2004...AlN substrate developer, Crystal IS of Watervliet, New York USA has closed
on $5 million of Series A venture funding. Investing in the innovative young
RPI-associated company that has made serious progress in the manufacture of
ultra-low defect density native aluminum nitride (AlN) single crystal substrates,
are ARCH Venture Partners, JVP, 3i, Harris & Harris Group, Inc., and a local
New York investor, Walt Robb. As a result of the financing, Keith Crandell from
ARCH, Zeljka Matutinovic from JVP and Sean Brownlee from 3i will join the Board
of Directors of Crystal IS’. One of the prime reasons this group has hitched
to the Crystal IS star is that nitride crystal substrates are now making important
inroads in stoplights, military applications, biomedical, information technology,
wireless communication, display lighting, as well as demonstrating significant
promise as future DVD and high power microwave devices. AlN substrates in general,
and Crystal IS' low defect substrates in particular, are gradually taking over
niche applications where the specs are especially tight and demanding. The company
is seeing special interest in four device sectors: UV LEDs and lasers, piezo
transducers (such as those being worked on by Michael Shur's group at RPI),
as high power RF transistors for military applications, and... depending on
the demands of the specs, as devices in white lighting, especially deep UV as
in DARPA's SUVOS program.The company is seeing special interest in four device sectors: UV LEDs and lasers for UV germicidal irradiation, bioagent and chemical sensing, white lighting research, and certain military applications (e.g., those anticipated under DARPA SUVOS), high power RF transistors for wireless base station and certain military applications, and next generation surface acoustic wave (SAW) devices (such as those being worked on by Michael Shur's group at RPI).
"We have assembled an exceptional technical team that has worked tirelessly
to grow our company and the potential for native aluminum nitride based commercial
applications. This investment leverages our success to date and will help us
to accelerate our technology and product roadmaps, expand our substrate production
capacity and quality, and further drive our collaborative device development
activities,” said Leo Schowalter, Crystal IS' President and CEO. Crystal
IS was founded in 1997 by Rensselaer Polytechnic Institute (RPI) physics professors
Glen Slack and Leo Schowalter. The company is located in the RPI Incubator Center,
which is well known for its technical services, support, and success rate for
startup companies. Albany NanoTech at the University at Albany has also provided
Crystal IS with strategic assistance including access to downstream semiconductor
materials processing capabilities. Crystal IS has a strong base of academic,
corporate, and government support for its technology. Company

More Industry LayoffsSeptember 29, 2004...We're all getting pretty tired of seeing that headline, but the reality is
that even more "adjustments" continue to be underway as companies
keep cutting back to the quick. Trick is not to cause bleeding. The latest companies
to quietly be laying off people are MBE equipment Riber of France and laser
maker Alfalight of Madison, Wisconsin in the USA. While no numbers were divulged
by Riber, IOP's print magazine, Compound Semiconductor, reported,
"As a result of the lackluster performance, the company is to reduce its
workforce and production expenses, partly by concentrating its operations onto
a single site." Meanwhile, in Wisconsin, 16 of Alfalight's current 38 member
workforce will be let go on September 30th. The layoffs range from senior Ph.D.s
to production staff members. And some of the bigger players are again in cutback
mode. Motorola, for example, is axing 1000 people as it nears completion of
spinning off Freescale. And Agere, which is now down to 6,600 people will cut
another 500 from its ranks soon and close its Florida plant (ref. Reuters
coverage) using the same rationale as TI and Intel of late, that the
culprit is the inventory buildup in the telecom and wireless side. As Dave Kang,
an analyst with Roth Capital Partners put it, "The industry went ahead
of itself and now we're seeing a correction." Actually, a number of
companies are closing shop in Florida as that USA state continues to get hammered
by major hurricanes. As Florida author, humorist, and popular columnist, Carl
Hiaasen explained, with his usual wit, "The hurricane's are Mother
Nature's annual eviction notice."

Vishay Makes A Colorful Splash with Six Colors of Bright LEDsSeptember 29, 2004...Vishay, a huge global company now employing 27,000 employees worldwide, is
making its presence known in the ultra high bright LED market, and they're doing
it by introducing six different colors of new surface mount LEDs that provide
luminous intensities ranging from 13 mcd to 80 mcd. The device family comes
in a small SMD form factor and feature ultra-miniature dimensions of 1.6 mm
by 0.8 mm and a low height profile of 0.6 mm. A list of each part number, color,
wavelength and brightness levels are included the company
