TAINAN, Taiwan -- Prof. Hwung-Hweng Hwung, the Senior Executive Vice President of National Cheng Kung University (NCKU) - Taiwan, on behalf of NCKU, signed a joint venture agreement with a privately owned Taiwan Nitride Material Inc. led by its chairman Mr. H.H. Chang, for the production of aluminum nitride (AlN). Both parties agreed to invest a total of NT$ 30 million (US$ 932,000) for research
and development of AlN, a semiconductor material widely used for heat radiation and insulation in microelectronics and optoelectronics.

NCKU will have a share right of 18% resulting from technique transfer and expects to have a revenue of at least NT$ 100 million (US$ 3.1 million) over the next ten years. The AlN production technique was developed by Prof. Shyan-Lung Chung of the NCKU Department of Chemical Engineering under the support from National Science Council (NSC) with an umbrella project, "A Study of Interdisciplinary Platform for New Technology Commercialization,
Academic-Enterprise Collaboration, and Entrepreneurship", supervised by the
principal investigator - NCKU SEVP Hwung-Hweng Hwung. This agreement is the
first joint venture in aluminum nitride production in Taiwan and certainly
created a new way of the commercialization in the cross field of new

The academia-industry collaboration is essential to promote industrial
development and innovation of our society. However, most universities in Taiwan
emphasized the mode of academia-industry collaboration in technology transfer in
the past few years, which often leads to a failure since no continuous R&D
creation has been put in from university. However, the new mode of
academia-industry collaboration has been reflected on the NSC-sponsored project,
"A Study of Interdisciplinary Platform for New Technology Commercialization,
Academic-Enterprise Collaboration, and Entrepreneurship", led by NCKU SEVP
Hwung. This new mode is to establish technical, marketing, producing and
financial analysis actively, to recruit the employees with competence and to
raise enough capital to realize creative and technical commercialization. That
is, academia and industry will be close partners even after signing the
agreement and finishing technology transfer. Prof. Hwung also expects to make
public announcement soon on another joint venture, under this project, in
production of aquaculture oral bacterial vaccine formulations and copper
resources recycling industry for the next 6 months.

"I have a wish. I hope to develop a product at my homeland to strengthen the
international competitiveness of local industry of my homeland. Now it is the
time for our earth with an emphasis in energy conservation and less carbon
emission. Light emitting diode (LED) provides a right solution to it. That is,
LED lighting is replacing iridescent bulbs. However, the life of LED is still of
grave concern resulted from overheating of the device. I really appreciated the
effort done by Prof. Shyan-Lung Chung on development of AlN products that could
solve this problem," said Mr. Chang, chairman of Taiwan Nitride Material Inc.

"In addition, Taiwan is known for its volume production of LED. The coverage and
luminescence intensity in LED lighting is increasing, and backlight modules for
LCD displays, made by LED, is prevailing. Moreover, AlN just solved the problem
in heat dissipation, frequently encountered in LED devices and the main cause of
failure to such devices, especially in lighting and large-size TV with higher
energy efficiency and less carbon emission. It also helps enhance the
competitive advantage of Taiwan's high-power LED lighting, such as street lamps
and backlight module industry. I hope this is a beginning for us as becoming
NCKU`s strategic partners, and there will be more collaborative opportunities
with each other in the future," said Mr. Chang, chairman of Taiwan Nitride
Material Inc.

Prof. SL Chung from NCKU Chemical Engineering Department has been dedicated to
researches on AlN for so many years. Prof. Chung has developed different
techniques, for example, sintering and composite materials, in efficient
production of AlN. There have been a number of manufacturers in close
cooperation with Prof. Chung`s laboratory in order to develop or to commission
test in AlN downstream products. AlN products are becoming more and more
popular, as its production cost is reduced with these innovative inventions by
Prof. SL Chung. Even more, these innovative inventions have been protected under
various issued patents and expect to generate high revenue.

It is worth to say that this cooperation project in the case of
cross-cooperation model for the first time from technology development,
technology transfer to technology commercialization, and mass production is done
by the same research team. It can promote the continuous technological
development and continuous mass production and product testing by the
newly-established company to shorten the technology development schedule, but
also to ensure that technology development is suitable for the demand of
business industry and customers.

About the project: A Study of Interdisciplinary Platform for New Technology
Commercialization, Academic-Enterprise Collaboration, and Entrepreneurship

The main objective of this project, "A Study of Interdisciplinary Platform for
New Technology Commercialization, Academic-Enterprise Collaboration, and
Entrepreneurship", led by NCKU SEVP Hwung is to integrate the related sources of
academia-industry, including the NCKU Research and Service Headquarter (RSH) and
the NCKU Technology Licensing and Business Incubation Center (TLBIC). They also
integrated six innovative sub-projects to cooperate with industry actively and
to drive incubation of novel invention, to give balance of capital and
innovative group planning and to establish a new company to realize the
commercialization of creative technology. These six project are "aquaculture
oral bacterial vaccine formulations research sub-research project", "health
development of Chinese herbal medicine research project", "copper loop resource
industries sub-research project", "biosurfactant products sub-research project",
"aluminum nitride production and development of innovative technologies
sub-research project" and "aluminum nitride electrical substrates metallization
sub-research project".

Innovative technological commercialization platform is aimed to establish a new
company from technological development to innovative incubation as a series of
service differed from the past academic innovation which is follow-up the
industry market development and operational management by technology transfer.
However, it is easy to break down the project due to technical fail-embracing in
promoting the process of convergence.

The technological value evaluation of innovative technologies in sub-projects of
"A Study of Interdisciplinary Platform for New Technology Commercialization,
Academic-Enterprise Collaboration, and Entrepreneurship" will come with a
relevant market demand, marketing and manufacturing feasibility and cost-benefit
assessment. They will invite manufacturers to participate closely, to send
technical members with the evaluation of various innovative technologies in the
process developmental feasibility and the technology in mass production of the
prototype development. They will set up an academia-industry collaborative
platform after technology development is mature; and then plan the management
team together, develop investment feasibility operating projects, raise funds,
and build up the factories and technology commercialization.

About Aluminum nitride (AlN)

Aluminum nitride (AlN) is a nitride of aluminum. Its wurtzite phase (w-AlN) is a
wide band gap (6.2 eV) semiconductor material, giving it potential application
for deep ultraviolet optoelectronics. AlN was first synthesized in 1877 but it
was not until the mid 1980s that its potential for application in
microelectronics spurred development of high quality commercially viable

AlN is synthesized by carbothermal reduction of alumina or by direct nitridation
of aluminum. It has a density of 3.26 g/cm3 and although it does not melt, it
dissociates above 2500°C at atmospheric pressure. The material is covalently
bonded and is resistant to sintering without the assistance of liquid forming
additives. Typically oxides such as Y2O3 or CaO allow sintering to be achieved
at temperatures between 1600 ~ 1900°C.

Aluminum nitride is stable at high temperatures in inert atmospheres and melts
at 2800 °C. In a vacuum, AlN decomposes at ca. 1800 °C. In the air, surface
oxidation occurs above 700°C, and even at room temperature, surface oxide layers
of 5 ~ 10 nm have been detected. This oxide layer protects the material up to
1370°C. Above this temperature bulk oxidation occurs. Aluminum nitride is stable
in hydrogen and carbon dioxide atmospheres up to 980°C.

The material dissolves slowly in mineral acids through grain boundary attack,
and in strong alkalies through attack on the aluminum nitride grains. The
material hydrolyzes slowly in water. Aluminum nitride is resistant to attack
from most molten salts, including chlorides and cryolite.

AlN is synthesized by the carbothermal reduction of alumina or by direct
nitridation of aluminum. The use of sintering aids and hot pressing is required
to produce a dense technical grade material. Metallization methods are available
to allow AlN to be used in electronics applications similar to those of alumina
and BeO.

Currently there is much research into developing light-emitting diodes to
operate in the ultraviolet using the gallium nitride based semiconductors and,
using the alloy aluminum gallium nitride, wavelengths as short as 250 nm have
been achieved. In May 2006 an inefficient AlN LED emission at 210 nm was

Among the applications of AlN are opto-electronics, dielectric layers in optical
storage media, electronic substrates, and chip carriers where high thermal
conductivity is essential, military applications, as a crucible to grow crystals
of gallium arsenide, steel and semiconductor manufacturing.

Epitaxially grown thin film crystalline aluminum nitride is also used for
surface acoustic wave (SAW) sensors deposited on silicon wafers because of the
AlN's piezoelectric properties. One application is an RF filter used in mobile
phones called a thin film bulk acoustic resonator (FBAR). This is a MEMS device
that uses aluminum nitride sandwiched between two metal layers.

The most remarkable property exhibited by AlN is its high thermal conductivity -
in ceramic materials second only to beryllia. At moderate temperatures (circa
200°C) its thermal conductivity exceeds that of copper. This high conductivity
coupled with high volume resistivity and dielectric strength leads to its
application as substrates and packaging for high power or high-density
assemblies of microelectronic components. One of the controlling factors which
limit the density of packing of electronic components is the need to dissipate
heat arising from ohmic losses and maintain the components within their
operating temperature range. Substrates made from AlN provide more efficient
cooling than conventional and other ceramic substrates, hence their use as chip
carriers and heat sinks.
