SkyWater Technology, the trusted technology realization partner, announced that it has completed its acquisition of Infineon Technologies AG’s 200 mm semiconductor fab in Austin, Texas (“Fab 25”). By adding approximately 400,000 wafer starts per year in capacity, Fab 25 brings meaningful scale to SkyWater’s exclusively U.S.-based, pure-play foundry operation and enables SkyWater to enhance its advanced technology services (ATS) offering by incorporating the site’s current capabilities. The facility will play a central role in expanding domestic manufacturing for foundational semiconductor technologies that support embedded processors/MCUs, memory, mixed signal, RF and power applications. In addition, the transaction advances the onshoring of semiconductor production by converting the fab’s capacity from serving a captive integrated device manufacturer (IDM) to operating as a pure-play, open-access semiconductor foundry.
This conversion significantly expands domestic foundry services for a broad base of SkyWater’s industrial, automotive, and defense customers. With the addition of Fab 25, SkyWater becomes the largest exclusively U.S.-based, pure-play foundry service provider offering dual-sourced support for foundational node, 200 mm foundry capacity. Further, SkyWater believes the move directly supports national onshoring and reindustrialization efforts aimed at strengthening the U.S. semiconductor supply chain. SkyWater is one of the only companies actively transforming captive U.S. IDM fabs into open-access infrastructure for secure, high-demand technologies, which is in alignment with U.S. Department of Defense supply chain security mandates.
“Today’s successful completion of the Fab 25 acquisition marks a pivotal moment in our ongoing effort to strengthen the U.S. semiconductor ecosystem,” said Thomas Sonderman, SkyWater CEO. “By transforming Fab 25 into an open-access, scalable foundry, we’re building on its impressive legacy while opening a new chapter that advances supply chain resilience, expands opportunities for our customers, and enhances U.S. competitiveness in the technologies critical to industrial infrastructure, defense systems, and the transportation and auto industries.”
Fab 25 provides high-volume capacity and advanced capabilities that are increasingly scarce in the U.S., reinforcing SkyWater’s ability to support secure, scalable production at foundational nodes. With proven capabilities in copper processing, high-voltage technology, and 65 nm node infrastructure, Fab 25 today becomes a critical piece of SkyWater’s exclusively U.S.-based foundry platform to meet growing customer demand and national security imperatives, and be fully integrated into its domestic, multi-node, multi-market foundry roadmap supporting innovation across a range of foundational chip technologies. Along with the transaction, both companies agreed on a long-term supply agreement that will enable Infineon to maintain a strong, efficient and scalable manufacturing footprint in the United States.
Approximately 1,000 Fab 25 employees have now joined SkyWater. The Austin site will continue to be a vibrant hub of semiconductor manufacturing expertise, with SkyWater investing to support long-term growth and new opportunities for employees and the surrounding community.
