#GFS #MRVL — GlobalFoundries Expands SiGe Capacity for AI Optics | ThinkSabio
Sep 18, 2026 · ThinkSabio Inc
GlobalFoundries (#GFS) and Marvell (#MRVL) have signed a multi-year agreement to expand U.S. silicon germanium (SiGe) manufacturing capacity at GlobalFoundries’ Burlington, Vermont facility.
🔹 Key Highlights
🤝 GFS and Marvell signed a multi-year manufacturing agreement.
🏭 Additional capacity will be added at GFS’ Burlington, Vermont facility.
🔌 The capacity will support Marvell’s pluggable, near-packaged and co-packaged optics.
🤖 AI data centers are driving demand for higher-bandwidth optical interconnects.
⚡ GFS’ current SiGe platform supports 200G-per-lane connectivity.
📈 The platform has a roadmap toward faster generations.
🇺🇸 Separately, Japan and the U.S. are reportedly discussing a potential $19.3B semiconductor fab that could be operated by GFS for logic-chip production.
💡 Why It Matters
AI data centers require increasingly high-bandwidth optical connections. Expanding SiGe capacity gives GlobalFoundries and Marvell additional manufacturing capacity to support next-generation AI optical infrastructure while a potential new U.S.-linked fab could further expand GFS’ manufacturing footprint.
