silicon germanium technical

"increase capacity for GF’s silicon germanium (SiGe) technology"

A semiconductor alloy made by mixing silicon and germanium to combine the strengths of both materials. Engineers use silicon germanium in electronic chips to boost speed, improve power efficiency, and handle high‑frequency signals—think of it as blending two metals to get a lighter, stronger alloy for specific jobs. It matters to investors because its use affects demand, manufacturing complexity, cost structures, and competitive positioning across chipmakers and their suppliers.

silicon photonics technical

"co-integrate SiGe, silicon photonics and advanced packaging"

Silicon photonics is the technology that uses tiny structures etched into silicon chips to generate, control and detect light for moving data and sensing, essentially putting optical fiber functions onto a computer chip. For investors, it matters because it can dramatically increase data speed and energy efficiency in data centers, telecom networks and advanced sensors, potentially lowering costs and enabling new products much like replacing many metal wires with faster, low-power optical highways.

co-packaged optics technical

"Near-Packaged Optics (NPO) and Co-packaged Optics (CPO)"

Co-packaged optics are optical components—lasers and fiber interfaces—physically packaged together with a network switch’s main processing chip so light-based data links sit much closer to the chip instead of traveling over long electrical traces. For investors, this matters because it can dramatically cut power use, boost data speed and density, and lower system costs in large data centers and telecom equipment, much like moving a power outlet next to a heavy appliance to avoid long, inefficient extension cords.

optical transceivers technical

"next-generation pluggable optical transceivers"

Optical transceivers are small hardware modules that convert electrical signals into pulses of light and back again so data can travel over fiber-optic cables; think of them as translators that let computers and network equipment “talk” over long distances at very high speed. They matter to investors because demand, supply constraints, and price changes for these components directly affect the growth and profitability of companies serving data centers, telecom networks, and cloud services, similar to how a shortage of car engines would impact auto makers.

Multi-year strategic agreement increases capacity for high-performance SiGe technology to support growing AI infrastructure demand

MALTA, N.Y., Sept. 17, 2026 (GLOBE NEWSWIRE) -- GlobalFoundries (Nasdaq: GFS) (GF) and Marvell Technology, Inc. (Nasdaq: MRVL), a leader in data infrastructure semiconductor solutions, today announced an expanded multi-year agreement to increase capacity for GF’s silicon germanium (SiGe) technology at its Burlington, Vermont, facility to support growing demand for next-generation optical connectivity.

Modern AI data centers operate as distributed compute systems, where performance depends not only on accelerators, but also on the high-speed interconnects that move data between them. As AI systems scale, moving data efficiently is becoming increasingly critical to overall performance. The expanded collaboration between GF and Marvell will increase capacity for high-performance SiGe technology used in next-generation pluggable optical transceivers, Near-Packaged Optics (NPO) and Co-packaged Optics (CPO).

The expanded agreement builds on existing production and is expected to add significant capacity to support Marvell’s growing requirements.

GF’s SiGe technology portfolio provides the high-frequency performance, signal integrity and power efficiency required for advanced optical networking applications. Its current technology supports 200G-per-lane optical connectivity, with a roadmap designed to address higher-speed generations as AI and cloud data center bandwidth requirements continue to grow. GF has manufactured advanced SiGe technology for over a decade and continues to co-integrate SiGe, silicon photonics and advanced packaging for new optical connectivity architectures including NPO and CPO.

“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.”

The agreement builds on more than a decade of collaboration between GF and Marvell and reflects the increasingly important role optical networking technologies play in enabling AI and cloud infrastructure at scale.
