Aixtron`s GaN-on-Si tool wins Aurora 2013 award

After being awarded at the CS awards for this tool the firm has been once again been recognised for its cost efficient MOCVD AIX G5+ reactor used for gallium nitride-on-silicon development
Aixtron SE was awarded the 2013 LEDinside Aurora Award in the category “Most efficient MOCVD Equipment” on June 11th, 2013.

Aixtron received the award for its AIX G5+ technology for Gallium-Nitride-on-Silicon (GaN-on-Si).

Aixtron’s system was chosen due to its production efficiency and technological advancement and was already awarded with the CS Industry Award in March of this year.

“Producing gallium nitride based LEDs on 200 mm silicon substrates is a promising route towards a much lower chip manufacturing cost,” comments Andreas Tönnis, Chief Technology Officer at Aixtron. “This second award within a short period of time again confirms the high degree of innovation of Aixtron’s R&D work in close cooperation with our customers.”

With the AIX G5+, Aixtron has created a novel 5 x 200 mm technology package for the existing AIX G5 HT for production of GaN-on-Si devices, offering the industry’s largest multi 200 mm MOCVD reactor. Manufacturers such as the US company Transphorm will build on Aixtron’s advanced GaN-on-Si expertise, expanding productivity from 150 to 200 mm diameter wafers, with the goal of fully exploiting economies of scale from the AIX G5+.

The well-known challenges of GaN-on-Si MOCVD processes are met by the novel features of the G5+ reactor, including modified temperature management, a new gas inlet and a chamber reset procedure. This results in minimization of wafer bow and elimination of so-called melt back effects, maximum process stability and highest uniformity due to a specifically designed rotational symmetry pattern.

 

Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
