MALTA, NY, Sep 21, 2026 – GlobalFoundries (GF) will expand silicon germanium (SiGe) manufacturing capacity at its Burlington, Vermont, facility to meet Marvell Technology’s optical connectivity demand. The multiyear agreement between GF and Marvell supports pluggable optical transceivers, near-packaged optics (NPO) and co-packaged optics (CPO).
GF’s SiGe technology supports 200G-per-lane optical connectivity. Its roadmap addresses higher-speed generations as AI and cloud data centers require more bandwidth. The SiGe portfolio provides high-frequency performance, signal integrity and power efficiency for optical networking applications.
GF also continues to co-integrate SiGe, silicon photonics and advanced packaging for optical connectivity architectures, including NPO and CPO. The capacity agreement builds on existing production and collaboration with Marvell.
“AI is fundamentally changing the way data centers are built, and connectivity is becoming increasingly critical to unlocking the performance of these systems,” said Robb Johnson, vice president, Foundry Technology, Marvell. “As the industry moves toward higher-bandwidth optical architectures, including NPO and CPO, Marvell is investing aggressively to lead this transition. Our expanded collaboration with GF will help ensure we have the SiGe technology and manufacturing capacity to support the significant growth we see ahead.”
“SiGe is where GF’s decades of high-performance radio frequency and analog leadership translate directly into breakthrough optical performance,” said Shankaran Janardhanan, senior vice president of Photonics & RF businesses at GF. “This agreement reinforces our long-standing relationship with Marvell and reflects the critical role SiGe technology plays in enabling high-speed optical networking for AI infrastructure. We will continue investing in our technology roadmap and manufacturing capabilities both in the U.S. and around the world to support our customers’ future growth.”
