Taiwan’s NCH University Selects Aixtron Reactor For GaN-on-Si Research

The MOCVD system will be used to investigate the heteroepitaxial growth of gallium nitride based alloys on silicon wafers, mainly for LED research

Aixtron SE has announced that National Chung Hsing University (NCHU), a new customer and technical university in Taiwan, has placed an order for one Close Coupled Showerhead (CCS) MOCVD system in a 3x2-inch wafer configuration.

NCHU will use the CCS system to research GaN-on-Silicon. One of Aixtron´s local service support teams has already installed and commissioned the new reactor in a dedicated cleanroom facility at NCHU’s site in Taichung, Taiwan.

Wuu, a professor at the Department of Materials Science and Engineering at NCHU, comments, “Aixtron’s Close Coupled Showerhead system is the ideal choice for the study of GaN-on-Silicon. This is not only my opinion from my years of familiarity with the technical challenges of these materials, but also the consensus of many leading researchers around the world who are using the Aixtron MOCVD system."

Horng, another professor at NHCU, based at the Graduate Institute of Precision, adds, “The reactor has demonstrated its versatility, ease of operation and reproducibility over the range of parameters of interest to us, we therefore will be able to produce high-quality GaN-on-Si epilayers and other novel structures."

Since 2001, the research team led by Wuu and Horng at NCHU has developed many unique LED technologies for both GaN and AlGaInP materials. Today, their integrated laboratory from epitaxial growth to device processing and packaging has established itself as one of the leading research centre in Taiwan. Many of its successful academic-industry cooperation projects have also been awarded by the National Science Council of Taiwan.

NCHU claims to be the only state-run university in central Taiwan that offers a comprehensive choice of both research and taught curriculum programmes. The institute has been investing in three centres of research excellence including biotechnologies, nano-biomimetics and advanced industrial precision instrumentation technologies, as it strives to become a world-class university over the next five years.

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.
