AIXTRON AG today announced
a new order for one CRIUS deposition system from the University of Duisburg-Essen.
The order was placed in the fourth quarter of 2009 and the system will be delivered
in the second quarter of 2010. AIXTRON’s local support team will commission
the new reactor at the University of Duisburg-Essen Semiconductor & Optoelectronics
Center in Duisburg, Germany. The system will be supplied in a 3x2-inch configuration
and comes equipped with a ARGUS multichannel pyrometer.
Prof. Dr. rer. nat. Franz-Josef Tegude, Chair of Semiconductor Technology,
comments, “We selected the AIXTRON CCS system as part of the University’s
initiative to acquire a nitride material system for the nitride nanowire NaSoL
Project. Our experience with AIXTRON equipment goes back a long way - we were
one of their very first customers. The reactor’s combination of features
including the minor/low rotational velocity is also very impressive. Overall,
we have always been very satisfied with the quality of AIXTRON engineering,
processes and service. Of course, we also took into consideration our project
partnership. The NaSoL Project aims to achieve production of GaN- and (Al,Ga,In)N-based
semiconductor nanowires for improved efficiency solar cells and LEDs. The AIXTRON
CCS system will provide us with a firm foundation for a smooth and rapid development
program for all our partners.”
NaSoL, which stands for “Halbleiter-Nanodrähte für Solarzellen
und Leuchtdioden”*) will result in a new generation of semiconductor nanowires
for solar cells and LEDs. The intention is to replace more costly traditional
semiconductor fabrication techniques with MOCVD. Nanowire-based materials have
a number of excellent characteristics and offer improved economics. They are
not only significantly more efficient both in absorption and in the emission
of light, but also promise very low losses in energy transport. The nanoscale
coaxial core-shell heterostructure of these devices has a larger surface area
so it absorbs more light and delivers better efficiency. In addition, the new
technological process offers device fabrication on lower cost substrates.
Partners in the NaSoL Project are AIXTRON AG, the University of Duisburg-Essen’s
Center for Semiconductor and Optoelectronics (ZHO) and the Department of Electronics
Materials and Nanostructures. Supported by the state of Northrhine-Westfalia,
the research project was formally approved and started during the third quarter
of 2009. The project is funded under the Objective 2-competition NanoMikro +
Werkstoffe NRW.
