DuPont Sells Compound Semi Business To SK Siltron

News

Korean wafer supplier to take over SiC wafer production to serve power electronics market

DuPont Electronics and Imaging (E&I) has signed an agreement to sell its Compound Semiconductor Solutions (CSS) business to SK Siltron, a silicon wafer supplier based in South Korea. The transaction is expected to close by the end of 2019, subject to customary regulatory approvals for closing.

"The DuPont CSS business has state-of-the-art technologies for SiC wafer production to serve the power electronics market, but it is not a strategic priority for the E&I business," said Jon Kemp, president, DuPont Electronics & Imaging. "Given its strategic focus, we believe SK Siltron will be a better owner and that the CSS business will thrive under SK Siltron's ownership."

According to SK Siltron, the SiC wafers will provide a solid foundation for a new generation of industrial motor controls and power supplies that use electricity more effectively while operating more efficiently. The company plans to combine its manufacturing capabilities with DuPont's research and development (R&D) to optimise processes.



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.
