Coherent opens SiC facility in Vietnam
Coherent, the US-based semiconductor and optoelectronics firm, opened a new facility in Vietnam onJuly 28 2025. The $127 million plant, in Nhon Trach Industrial Park in Dong Nai province, will make SiC semiconductors, optical glass, and advanced optoelectronic components.
Speaking at the opening ceremony, deputy prime minister Nguyen Chi Dung underscored the move by Coherent as compelling evidence of the growing confidence that leading global tech firms are placing in Vietnam’s investment environment and development potential.
"Vietnam is actively developing key strategic industries, including semiconductors. Today’s event is a concrete step in implementing the Joint Statement on upgrading Vietnam-US relations to a Comprehensive Strategic Partnership. Coherent is expected to make a meaningful contribution to Vietnam’s emergence as a key link and future hub in the global semiconductor supply chain," said Dung.
Coherent entered Vietnam in 2005, establishing its first factory at VSIP1 Industrial Park in former Binh Duong province, specialising in thermoelectric coolers, technical ceramics, wafers, advanced optics, and laser services. In the late 2010s, Coherent expanded to the north, and in 2019 opened a facility at Yen Phong Industrial Park (IP) in Bac Ninh province.
In 2023, Coherent met with Dong Nai provincial leaders to propose three high-tech projects at Nhon Trach 1 & 2 IPs, including SIC, semiconductor manufacturing, advanced optics, and the M-Cubed project for measurement, testing, and semiconductor component production.
Gan YC, director of Nhon Trach 1 Factory, said: "This new facility is designed with scalability, flexibility, and sustainability at its core, to meet the rising global demand for advanced technologies. It plays a pivotal role in enhancing our capabilities in SiC and optics, both essential to the transformation of industrial systems, high-speed communications, and data centre infrastructure. Equipped with smart manufacturing systems and a high-quality local workforce, the factory strengthens our supply chain, reduces lead times, and brings us closer to key markets across Asia. This is not merely a factor, it is a strategic platform for innovation, growth, and long-term competitiveness," said YC.
Nguyen Minh Man, general director of Coherent Vietnam (Dong Nai) believes the inauguration of Coherent Corporation’s new factory in Vietnam marks a significant step forward in its global growth strategy. "It reinforces our long-term commitment to Southeast Asia, a vital region for advanced manufacturing, technological innovation, and talent development," said Man.
