Adoption Of SiC & GaN To Impact The Power Electronics Industry

Emergence of new wide bandgap (WBG) technologies such as SiC and GaN materials will definitely reshape part of the established power electronics industry, according to Yole Développement (Yole). SiC and GaN benefits are now well known. Indeed such materials offer: higher frequency switching "“ higher power density "“ higher junction temperature "“ higher voltage capabilities.

Yole will present its vision of the Power Electronics Industry, at the Power Electronics Conference "The ultimate path to CO2 reduction," taking place from October 8th to 9th, in parallel of SEMICON Europa 2014. During the conference, Yole will detail the status of the Power Electronics industry, its technology trends and related players, taking into account the introduction of new materials such as SiC and GaN.

From the silicon carbide side, its adoption for train applications is a main trend. It confirms that SiC could play an important role in the high and very high voltage ranges (up to 1.7kV) in a near future.


"At Yole, we stay convinced that these voltage and related power ranges, are exactly the place-to-be for SiC technology," says Pierric Gueguen, Senior Market Analyst, Power Electronics at Yole Développement (Source: SiC Modules, Devices and Substrates for Power Electronics report, October 2014).

Last June, Yole released its Power GaN Market report confirming as well the introduction of GaN in the Power Electronics market. Yole's analysts identify numerous applications, especially for low voltage range such as power supply/PFC. According to this technology & market analysis, the power supply/PFC segment will dominate the business from 2015 to 2018 with 50 percent of the device sales.

However, with such new wide bandgap (WBG) technologies, industrials face new technical challenges. Indeed, current packaging solutions do not answer to GaN and SiC specifications. Under this context, some companies develop a new enhanced package strategy to improve performances. According to Yole, based on these new packaging solutions, the power modules market should reach US$ 200 million in 2016.

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.
