Aixtron Systems To Power Up SINANO's Nitrides

One reactor will be used to grow production GaN-on-silicon wafers and HEMTs. The 2-inch R&D system is intended for growing gallium nitride lasers
The Suzhou Institute of Nano-tech and Nano-bionics (SINANO), China, has ordered two Aixtron Close Coupled Showerhead (CCS) systems.

The reactors will extend the centre’s nitride semiconductor research.

The order was placed in the third quarter of this year, with deliveries planned in the fourth quarter of 2012 and in the first quarter of 2013.

One system, capable of handling 6x2-inch substrates, focuses primarily on R&D. The other system, a CRIUS, is designed for mass production. It is capable of handling up to 31 x 2-inch or 3 x 6-inch substrates in one run.

Hui Yang, Director of SINANO, says, “Our Nano-Devices and Materials Division will use these systems to develop new applications such as GaN lasers on the 2-inch R&D system and GaN growth on silicon substrates and high electron mobility transistors (HEMT) on the CRIUS system."

The Nano-Devices and Materials Division was established in 2006, with one of its research groups focusing on GaN-based high power LED and laser diodes with an Aixtron CCS 6 x 2-inch system. The division now wants to extend its expertise into the power electronics field.

GaN-based HEMTs are being widely developed on silicon as a route to mass production of high power density devices for radio frequency and power switching applications. Systems built with such devices could be more compact and more power efficient, needing less complex circuitry with fewer passive components and reduced cooling requirements.

SINANO was founded by the Chinese Academy of Science, the government of Jiangsu Province and the government of Suzhou city. The centre’s mission is to carry out fundamental, strategic and prospective research, aiming at world-class technological advancement, meeting China’s national strategic demand and leading the way to future industrial development.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
