a question of time before a pullout from magnetics technology would take place. In our efforts to secure the future of Tridonic in this decisive phase of the technology shift to LEDs, this is the right time to make a coordinated withdrawal from the magnetics sector,” says Tridonic CEO Alfred Felder.
He adds, “Of course we regret this step in view of the employees who are affected. Through their commitment they have played their part in Tridonic’s success for many years. We are not only grateful for this but also want to assure them that we will live up to our responsibility towards them in full.”
Withdrawal from the magnetics business will also mean the closure of two Tridonic production plants located in Fürstenfeld, Austria and Melbourne, Australia, with the loss of 102 jobs in Fürstenfeld and 49 in Melbourne.
Tridonic management will be working closely with the employee representatives in Austria and the trade union in Australia to arrive at balanced solutions for the affected employees.
As an alternative to closure of the Melbourne factory on 30th December 2013, we are currently engaged in intense negotiations with a potential investor who will continue to employ the majority of the workforce in the event of a takeover. No decision has yet been made in this respect.
NASA to branch out into multiple compound semiconductors
Using MBE or MOCVD equipment, NASA Langley is seeking a facility for III-V semiconductor epilayer growth
NASA LaRC says it will fabricate and deliver a total of 60 wafers during 6 months.
Among these wafers, at least twenty wafers will be processed to fabricate multiples of working devices. The device fabrication will use silicon oxide/nitride deposit, photo-lithography with mask-aligner, wet and dry etching and thermal diffusion.
CONTRACTOR TASKS
The company says that it wants contractors to provide III-V compound semiconductors which include:
1. GaAs, InAs, AlAs 2. GaP, InP, AlP 3. GaAsN, InGaAsN
The service provider should also be prepared to provide the following:
1. X-ray diffraction analysis
2. Standard CMOS micro-fabrication capability 3. An additional nitrogen plasma source as well as III-V compound semiconductor sources
4. P-type and n-type dopant control (effusion cells or similar)
5. In-situ characterisation during epi-layer growth 6. Metallisation capability 7. Automatic growth rate and doping level control
GOVERNMENT FUNISHED MATERIAL
Special substrate wafers for III-V compound semiconductor epi-layer growth will be provided by NASA Langley. Device structure and epitaxy growth methods will be guided by the NASA Langley’s research team.
The intellectual properties of patented growth methods, characterisation methods, epilayer structures, and device structures & fabrication methods will belong to NASA Langley. And NASA says no intellectual properties will be exchanged.
PERIOD OF PERFORMANCE
The period of performance will be 6 months after receipt of order.
Osram Opto awarded green supplier of the year
The firm’s III-nitride LEDs have been awarded by automotive supplier, Yazaki North and Central America
Yazaki North America has named Osram Opto Semiconductors as a “Green Supplier of the Year” at its annual awards ceremony.
Yazaki also recognised Osram Opto Semiconductors as the “Best in Class Green” supplier for 2012-2013 honouring them with both awards of excellence.
Osram was chosen from Yazaki’s top 103 suppliers in North and Central America.
“Yazaki’s Green Supplier of the Year program is another way that we reinforce our commitment to helping create a society capable of sustainable development,” comments Olga Alavanou, executive vice president, Supply Chain Management for Yazaki. “Working together we can make a difference, and I am pleased to honour Yazaki suppliers whose commitment to the environment is as
