Support for next-generation electronic devices such as automotive DC/DC converters and industrial PFCs
"We will grow into a global leader in the power semiconductor field with our power GaN roadmap"

STMicroelectronics announced on March 17 that it has agreed to acquire a majority stake in Exagan, a French GaN company.
Through Exagan's expertise in epitaxy technology, product development, and application know-how, ST plans to accelerate its power GaN roadmap and business expansion for automotive, industrial, and consumer applications.

The terms of the transaction are confidential, and the closing of the acquisition is subject to customary regulatory approval by French authorities. Under this agreement, ST will acquire the remaining minority stake in Exagan 24 months after the closing of the majority stake. Transaction funds are provided through available cash.

"ST CEO Jean-Marc Chery said, 'ST has built strong momentum in the silicon carbide sector and is leading the market by expanding into another high-potential composite, gallium nitride, to accelerate the adoption of GaN-based power products by customers across the automotive, industrial, and consumer markets. The acquisition of a majority stake in Exagan is another step forward to strengthen our technological capabilities in the power semiconductor sector, as well as our GaN long-term roadmap, ecosystem, and business. We are continuing our collaboration with TSMC alongside the development project currently underway with CEA Leti in Tours, France.'"

Gallium Nitride (GaN) is a material belonging to the wide bandgap (WBG) material group, which includes silicon carbide. GaN-based devices are a major next-generation solution for power electronics, providing high-frequency operation. They offer superior efficiency compared to silicon-based transistors and high power density, enabling power savings as well as a reduction in overall system size.

GaN products currently support applications in various fields, including Power Factor Correction (PFC) and DC/DC converters for servers, communications, and industrial applications, as well as DC/DC converters for automotive applications and personal electronics applications such as onboard chargers and power adapters for EVs.
