BluGlass Awarded Nearly $3 Million Clean Technology Innovation Grant
CompoundSemi News Staff
July 29, 2013...BluGlass Limited of Australia announced that it has been awarded $2,999,255
in government funding for the company’s ‘versatile prototype
deposition machine for higher efficiency, energy saving, lower cost LEDs on
various substrates including silicon’. The project is funded through
Australian Federal Government as part of the Clean Technology Innovation
The project aims to significantly reduce the greenhouse gas emissions
generated in producing LED devices. BluGlass claims its unique low temperature
Remote Plasma Chemical Vapor Deposition (RPCVD) technology offers device
manufacturers significant performance and cost advantages. The company
estimates that for each RPCVD tool put into production could reduce greenhouse
gas emissions of more than 39,000 tons of CO2 equivalent per RPCVD unit (based
on 3.5 million LED lamps per annum).
The company plans to use the funding to accelerate research and development
of GaN on silicon substrates. Silicon is a low cost, large diameter substrate
that is currently limited in its application for LED semiconductor material
growth. Bluglass asserts that this is because the high temperatures of MOCVD
growth generally lead to bowing of the substrate, which leads to poor
manufacturing yields. However, RPCVD is a low temperature process.
BluGlass CEO Giles Bourne today said “We are delighted to have
been awarded this funding support for the continued advancement of our RPCVD
technology. This represents an enormous commitment from the Commonwealth
Government and demonstrates their continued belief in our ability to bring our
breakthrough technology to market."

Sol Voltaics Gets $6 Million Loan from Swedish Energy Agency
CompoundSemi News Staff
July 1, 2013...Sol Voltaics of Lund, Sweden, reported that the Swedish Energy Agency (SEA)
has granted the company a $6 million conditional loan to further the commercial
development of the company’s Solink technology. Solink is the company's
gallium arsenide (GaAs) nanowire material for solar modules, which promises
more efficiency. The loan is one of the largest ever issued to a company by the
SEA. The company also announced that Erik Sauar, who served for more than ten
years as the CTO and senior v.p. at solar manufacturer REC, has become an
The company points out that gallium arsenide is the most efficient solar
material available, but it is expensive. Sol Voltaics says it solves this
problem by minimizing the amount of gallium arsenide needed so less than a gram
of nanowires is required to produce Solink-enhanced modules. The company says
that each gallium arsenide nanowire in Solink, acts as an independent solar
cell. Therefore, the company says that a Solink-enhanced module is a vertically
stacked device that generates energy from a wider light spectrum than a
standard solar panel. According to Sol Voltaics, Solink is applied to
conventional solar panels toward the end of the existing module production
process with standard equipment using the company’s process called
Viveca Johansson, program manager at the SEA. stated, “The
technology developed by Sol Voltaics holds the potential to simultaneously make
solar competitive with fossil fuels at market prices while increasing the
business case for developers and manufacturers.”
'LAST POWER' Project Reports Achievements
CompoundSemi News Staff
May 20, 2013...'LAST POWER', the EU program to develop reliable and economical power
electronics, recently reported on the project's achievements. The project was launched in
2010 through the European Nanoelectronics Initiative Advisory Council (ENIAC)
Joint Undertaking (JU), which links private companies, universities and public
research centers to study of wide bandgap semiconductors (SiC and GaN). ‘LAST POWER’ is an acronym for 'Large Area silicon carbide Substrates and heTeroepitaxial GaN for POWER device applications'.
The main achievements stemmed from SiCrystal’s development of 150mm
diameter substrates with a cut-off angle of 2°-off axis with comparable quality
to the 100mm 4°-off material available at the project’s beginning. At
LPE/ETC, a novel CVD (Chemical Vapor Deposition) reactor was employed to
fabricate 600-1200V JBS (Junction Barrier Schottky) diodes and MOSFETs on 150mm
4H-SiC. The JBS diodes on 150 mm substrates had electrical performance
comparable with the state-of-the-art 4°-off material. Chemical mechanical
polishing (CMP) process, StepSiC ® reclamation and planarization from NOVASiC, enabled the JBS fabrication. The same company also developed epitaxial growth process for fabricating both MOSFET and JFET devices.
Acreo and FORTH with the support of CCR, jointly developed novel modules for
high-temperature 4H-SiC JFETs and MOSFETs. CCR studied molding compounds and
“lead-free” die-attach materials for reliable packaging.
ST Microelectronics also successfully produced AlGaN/GaN HEMTs epitaxial
structures with a 3 μm thickness and 200V breakdown. Last Power collaborated
with IMM-CNR, Unipress, and ST to develop ‘gold free’ production
for normally-off AlGaN/GaN HEMTs that is fully compatible with the fabrication
process at the ST production line.
Research into High-thermal-conductivity Substrates for GaN Electronics Gets UK Funding
CompoundSemi News Staff
April 29, 2013...Researchers from the University of Bath and the University of Bristol will
receive funding totaling more than £823,800 from UK’s Engineering and
Physical Sciences Research Council (EPSRC) over the next three years years. The
project is to develop highly thermally conductive substrates for GaN
A £430,597 grant (EPSRC reference EP/K024337/1) was awarded to the
University of Bath’s Department of Electronic and Electrical Engineering
with principal investigator Dr DWE Allsopp joined by professor W Wang. A
£393,218 grant (EPSRC reference EP/K024345/1) goes to the University of
Bristol’s Department of Physics, with principal investigator professor M
Kuball and professor D Cherns. IQE Silicon Compounds Ltd, NXP Semiconductors UK
Ltd and Plessey Semiconductors Ltd will partner with the University of
According to the researchers, AlGaN/GaN high electron mobility transistors
(HEMTs) will enable future power conditioning applications, and be used for high
efficiency military and civilian, microwave and RF systems. The researchers
note that although the performance of AlGaN/GaN HEMTs presently reaches RF
powers up to 40W/mm, at frequencies exceeding 300 GHz, its reliability, which
is often thermally limited, is a serious issue.
The project aims to mitigate this issue through developing novel substrates
that have higher heat extraction capabilities than SiC and developing low cost
substrates that have improved heat extraction compared to GaN-on-silicon for
more cost sensitive power electronics. The researchers assert that improvement
in heat spreading will imcrease reliability and circuit efficiency and ease Gan
