GlobalFoundries (GF) has made a pivotal step to advance its leadership in silicon photonics as it acquired the Singapore-based silicon photonics maker Advanced Micro Foundry (AMF).

With the buyout, GF is expanding its silicon photonics technology portfolio, production capacity, and research and development (R&D) in Singapore. Moreover, this will complement also its existing technology capabilities in the United States and will unlock new market opportunities with a broader set of AI datacenter and communication technologies.

Meets Evolving Industry Demands

Traditional copper connections are reaching its physical limits. Silicon photonics has emerged as a breakthrough technology that uses light to transfer data between and within data centers. Thus, delivering ultra-fast, energy-efficient performance.

As GF continues to expand its U.S. manufacturing capacity for silicon photonics in New York, this acquisition accelerates the ramp of our Singapore operation, enhancing supply chain resilience.

GF’s acquisition of AMF brings together AMF’s manufacturing assets, extensive intellectual property and skilled talent to significantly expand GF’s silicon photonics technology and establish the company as the largest silicon photonics pure-play foundry by revenue.

Leveraging over 15 years of AMF’s manufacturing expertise, GF will address demands in long-haul optical communications, computing, LiDAR and sensing on AMF’s 200mm platform in Singapore with plans to scale to 300mm as market needs grow. Therefore, ensuring reliable global supply for AI datacenters, communications and next-generation applications.

Tim Breen, CEO of GF, said acquiring AMF enables the company to deliver an expanded roadmap for pluggable transceivers and co-packaged optics. Moreover, it also accelerates growth of photonics into adjacent markets such as automotive and quantum computing.

“Silicon photonics technology is essential for AI infrastructure. As data moves faster and workloads grow more complex, the ability to move information with greater speed, precision and power efficiency is now fundamental to AI datacenters and advanced telecom networks,” said Breen.
