News Release Raytheon Reaches Milestone in Testing GaN Circuit Lifetime CompoundSemi News StaffJanuary 11, 2007...Raytheon reported achieving a testing milestone for gallium nitride semiconductor
technology. Ratheon’s Integrated Defense Systems division developed GaN
semiconductor circuits which recently went through a strenuous 8,000 hours of
operational testing. The monolithic microwave integrated circuits (MMIC) for
military radar, communications, electronic warfare, and missile systems, went
through testing conducted at elevated temperatures and more extreme operating
conditions to simulate performance over about 80,000. According to Raytheon,
this equates to more than nine years of non-stop normal operation. Raytheon
says it plans to continue accumulating test hours on the circuits into 2007.
The company also will run concurrent testing into 2007.
According to Raytheon, GaN semiconductors offer substantially improved power
and functionality beyond current semiconductor technologies. They operate at
higher voltage levels allowing significantly greater power output for the same
size chip. Additionally, the material characteristics of GaN semiconductors
allow efficient multi-band or wideband operation. Raytheon pointed out that
GaN technology used in radar can reduce the antenna size by half while more
than doubling the search volume. This improves the radar's transportability
and reduces acquisition and lifecycle costs. Company

interruptor (GFDI) for commercial photovoltaic inverters. According to SatCon,
the purpose of the GFDI is to detect low levels of ground currents and interrupt
any faults within specified limits. SatCon has developed and installed GFDI
for its photovoltaic systems well before the electrical protection system becomes
mandatory for photovoltaic that interconnect with electrical power systems under
UL1741 by May 7, 2007. SatCon says PowerLight Corporation is the first to install
its new GFDI device.
The UL1741 standard from Underwriters Laboratory is the electrical engineering
standard to safely convert DC photovoltaic power into AC power. While other
companies have made solar inverters that comply with previous versions of the
UL1741 standard, SatCon contends it is the first to offer a solar inverter that
complies with the latest soon-to-be mandatory UL1741 standard. SatCon
News Release Lockheed Martin Demonstrates Solid State Radar Antenna CompoundSemi News StaffJanuary 9, 2007...Lockheed Martin reports that it has completed a successful demonstration of
its solid state radar antenae with open architecture software. Lockheed Martin
(Lockheed) says it was able to display live tracks with its internally developed
Scalable Solid-State S-band Radar (S4R) Engineering Development Model (EDM).
According to Lockheed, the live tracks demonstrate the company’s proven
approach to an active antenna-based radar system designed with commercial hardware
and open architecture software. The S4R EDM system, developed using silicon
carbide (SiC)-based high-power transmit and receive (T/R) modules, is an electronically
steered radar system, which can support air surveillance, cruise missile defense,
ballistic missile defense, counter target acquisition, and littoral
operations.
The company points out that SiC provides greater power than other commonly
used materials due to its increased heat tolerance. With more power, the radar
has longer range and provides more precise target discrimination. Lockheed derived
the proven design of from the S-band antenna developed for the U.S. Navy's Volume
Search Radar on the DDG-1000 next-generation destroyer. Lockheed indicated that
the transmit/receive modules, the most critical components of a solid state
antenna, serve as multiple function circuits that generate and transmit signal
power over the full face of the radar, receive the reflected radar signal, amplify
it for processing, and electronically steer the radio frequency beams in space.

News Release Fairchild Plans Appeal of China Court Ruling CompoundSemi News StaffJanuary 8, 2007...Power electronics company, Fairchild Semiconductor, reports that it plans to
appeal the court ruling in China in favor of Zhongxing Telecom Ltd. (ZTE). The
Intermediate People's Court of Shenzhen, Guangdong Province, People's Republic
of China ordered Fairchild to pay RMB65,733,478 (approximately $8.4 million
at current exchange rates) to ZTE for damages in the product liability lawsuit.
Fairchild Semiconductor maintains that the product liability claims are invalid.
Fairchild says it will appeal to the Higher People's Court of Guangdong Province.
According to Fairchild, the lawsuit relates to alleged defects in products
shipped in late 2002 and early 2003. Fairchild says it did not sell the allegedly
defective products to ZTE directly. Among other defenses, Fairchild has argued
that limitations on damages in its contract with its distributor at the time
of shipment should limit any damages recovered by ZTE. Fairchild expects to
record a charge of approximately $8.2 million in the fourth quarter 2006 related
to the legal proceeding. Fairchild

News Release Warner Bros. and LG Electronics Choose Neutrality in DVD Format War CompoundSemi News StaffJanuary 5, 2007...For consumers and an industry that can’t decide which new DVD format
to back, movie studio, Warner Bros. has chosen to back both, according to an
article
by the Associated Press. The company, a unit of Time Warner Inc., has taken
the additional step of creating a single DVD it has dubbed the “Total
HD Disc” with both the HD DVD format created by Toshiba and the Blu-ray
format developed by Sony. Warner Bros. is not alone in choosing neutrality in
the DVD format war, Paramount Pictures, a unit of Viacom Inc., has chosen to
release movies in both formats. LG Electronics of South Korea also announced
it will soon introduce what one might call a “neutral” DVD player,
which can play both Blu-ray and HD DVD discs. LG
Electronics News Release.
However, the format war is far from over with movie studios and consumer electronics
makers taking sides. With either choice, the compound semiconductor industry
wins because both formats require blue laser diodes made of gallium nitride.
Twentieth Century Fox, which is owned by News Corp, and Walt Disney Co. have
staunchly supported the Blu-ray format. Universal Studios is perhaps the only
major studio thus far to choose to release movies only in the HD DVD format.
Consumer electronics giants, Toshiba, and Panasonic have will make players and
recorders only in the HD DVD format. The only critical team not yet taking sides
is the group of consumers. So far few have chosen one or the other, and instead
have chosen to wait until the issue is resolved to make the necessary investment
for a player and or recorder and all new format movies. Solar Thin Films to Collaborate With Renewable Energy Solutions CompoundSemi News StaffJanuary 4, 2007...Solar Thin Films (STF) of Budapest, Hungary reports that it has entered into
a three-year agreement with Renewable Energy Solutions Inc. (RESI) to develop
manufacturing equipment for copper indium gallium selenide (CIGS)-based thin
film photo voltaic modules. STF estimates that about 90 percent of the modules delivered
worldwide in 2005 used crystalline and polycrystalline silicon PV technology. For this
reason, the company says that the PV industry has recently experienced a shortage
of electronic grade silicon used in the crystalline silicon PV modules. Now
STF along with many of the major crystalline silicon PV module suppliers have
begun work in thin film-based photovoltaic materials because of both their efficiency
advantages and the fact that they are not affected by crystalline silicon shortages.
At the same time, STF is participating with RESI in providing a contract
proposal responding to the Solar America Initiative (SAI) for the optimization
of the CIGS technology presently held by RESI. The main US governmental and
university institutions, NREL (National Renewable Energy Laboratories), IEC
(Institute of Energy Conversion), and PNNL (Pacific Northwest National Laboratory),
have also participated in this proposal. The proposal reportedly covers a three-year optimization
of the CIGS technology now existing at RESI. "With this R&D contract
with RESI, STF plans to introduce module manufacturing equipment to produce
the next generation that will be more efficient and lower cost thin film CIGS-based
PV modules on a glass substrate," commented Csaba Toro, the CEO of STF.
STF says its goal is to begin selling the CIGS manufacturing equipment during the 2007 fiscal year. Ultimately STF says it wants to become a world leader in providing
turnkey facilities for CIGS-based thin film PV modules. Dr. Zoltan Kiss, a director,
consultant and significant shareholder of STF, is also a shareholder, director
and chief technical officer. Solar
