SK keyfoundry Expands Collaboration with Elmos on 130nm Technology and Signs Long-Term Wafer Supply Agreement

SEOUL, South Korea, Sept. 9, 2026 /PRNewswire/ -- SK keyfoundry, an 8-inch pure-play foundry in Korea, announced that it has recently signed an agreement with Elmos Semiconductor SE (hereafter referred to as Elmos), a leading global supplier of mixed-signal semiconductors for the automotive industry, to expand their collaboration on 130nm technology and secure a long-term wafer supply contract.

During a recent signing ceremony held in Frankfurt am Main, Germany, the two companies agreed to further advance their successful business relationship, which has been based on 350nm technology for the past 18 years. Under the new agreement based on the 130nm platform, SK keyfoundry will provide Elmos with stable wafer production capacity through 2037.

SK keyfoundry's 130nm technology features deep-trench isolation (DTI), enabling effective electrical isolation and facilitating highly integrated, high-voltage designs with low substrate current. This is expected to provide a solid foundation for the development of a wide range of new products.

Elmos' first product developed based on SK keyfoundry's 130nm platform is the E550.01 smart 4-channel eFuse controller. The product intelligently protects and controls complex multiple current paths, supporting zonal vehicle architectures, a key element of next-generation vehicles. It is scheduled to enter full-scale mass production in 2027. In addition, the two companies plan to jointly launch a new, highly compact and efficient eFlash memory cell.

Through this agreement, Elmos has secured a stable, long-term foundry supply partner. Meanwhile, SK keyfoundry expects to continuously expand its market presence and revenue share in the automotive semiconductor market over the long term by further strengthening its collaboration with a key automotive semiconductor customer.

"SK keyfoundry has been a reliable and innovative partner for many years, this new contract lays an excellent foundation for our future collaboration," said Dr. Arne Schneider, Chief Executive Officer of Elmos Semiconductor SE. "The additional wafer capacity ensures planning certainty through 2037, thereby strongly supporting our supply reliability and continued growth."

"We are pleased to expand our collaboration with Elmos, a leading supplier of automotive semiconductors, to include 130nm technology," said Derek D. Lee, CEO of SK keyfoundry. "Building on SK keyfoundry's strong technology platform, we will pursue our shared goal of developing innovative semiconductor solutions for automotive electronics. At the same time, we will continue to expand our supply of automotive semiconductors and strengthen our competitiveness as a global foundry."
