TL;DR
Coherent has initiated construction on a new facility in Sherman, Texas, to expand manufacturing of indium phosphide wafers used in AI data transfer. The project, supported by a $50 million CHIPS Act grant, aims to strengthen domestic supply chains for AI infrastructure components.
Coherent has officially broken ground on a new manufacturing building in Sherman, Texas, to expand its capacity for producing indium phosphide wafers used in optical data transfer for AI systems. The project is backed by a $50 million CHIPS Act grant, marking a significant step in domestic semiconductor manufacturing for AI infrastructure.
The new facility in Sherman will scale up production of 6-inch indium phosphide wafers, which are essential for high-speed optical interconnects in AI data centers. The expansion follows years of industry and government efforts to bolster U.S. semiconductor supply chains, particularly for compound semiconductors that enable light-based data transfer.
Jensen Huang, CEO of NVIDIA, and Jim Anderson, CEO of Coherent, attended the groundbreaking event, emphasizing the importance of domestic manufacturing for AI development. NVIDIA’s recent $2 billion investment in Coherent aims to support R&D and capacity expansion, aligning with broader U.S. initiatives like the CHIPS Act.
The expanded Sherman facility is expected to create more than 550 direct jobs once operational, along with thousands of indirect roles, according to Anderson. The project builds on previous support from Texas and local economic development programs, totaling over $67 million in combined funding.
Why This Expansion Accelerates AI Infrastructure Development
This expansion is a key step toward reducing reliance on overseas supply chains for critical optical components used in AI data centers. By increasing domestic production of indium phosphide wafers, the U.S. aims to secure its position in the global AI race, improve supply chain resilience, and support the growth of high-performance computing infrastructure.
Furthermore, the project exemplifies how government incentives like the CHIPS Act are translating into tangible manufacturing investments, potentially influencing industry standards and competitiveness. It also highlights the strategic importance of compound semiconductors, which are vital for high-speed, energy-efficient data transfer in AI systems.

Background of U.S. Semiconductor Manufacturing and AI Infrastructure
Historically, the U.S. led in semiconductor innovation but has seen manufacturing capabilities shift overseas, especially for compound semiconductors like indium phosphide. The technology was developed in U.S. labs in the 1970s but has since been produced mainly in Asia and Europe, with limited domestic capacity.
Recent initiatives, including the CHIPS Act passed in 2022, aim to bring semiconductor manufacturing back to the U.S., focusing on both logic chips and specialty components like optical wafers. Industry leaders like NVIDIA are investing heavily in domestic capacity, recognizing the strategic importance of these components for AI and high-performance computing.
The Sherman facility’s expansion represents a milestone in this effort, with the first 6-inch indium phosphide line in the U.S. now being significantly scaled up after decades of smaller-scale production on 3- and 4-inch wafers, which have lower yields and higher costs.
“AI is the ultimate general-purpose technology, affecting every industry, and domestic manufacturing of optical components is vital for its growth.”
