Nvidia Corporation has signed a multi-year strategic partnership with Amkor Technology featuring a $1.5 billion prepayment to expand advanced semiconductor packaging and test capacity within the United States. The deal aims to eliminate one of the most persistent bottlenecks in the artificial intelligence hardware supply chain: advanced 2.5D and 3D chip packaging. By providing upfront capital to Amkor, the world’s leading AI graphics processing unit maker is securing domestic packaging capacity for its next-generation data center processors and high-speed networking chipsets.
The financial market reacted with immediate enthusiasm to the multi-billion-dollar accord. Shares of Amkor Technology surged 16.6% in extended trading following the official disclosure of the deal. Under the terms of the agreement, Nvidia’s $1.5 billion cash prepayment directly funds the development of specialized cleanrooms, high-density substrate tools, and automated testing machinery at Amkor’s expanding manufacturing complex in Peoria, Arizona.
Advanced chip packaging has become as critical as raw silicon manufacturing for modern artificial intelligence systems. Top-tier AI processors, such as Nvidia’s Blackwell and future Rubin architectures, combine multiple silicon dies and High Bandwidth Memory modules on a single silicon interposer. Amkor’s facility will focus on high-density interconnects and complex heterogeneous integration, allowing disparate silicon chiplets to communicate with massive bandwidth and ultra-low power consumption.
The partnership completes a crucial missing link in the domestic semiconductor manufacturing ecosystem. Taiwanese foundry giant TSMC is currently building massive wafer fabrication plants in Phoenix, Arizona, to manufacture advanced 3-nanometer and 2-nanometer wafers. Previously, completed wafers manufactured in the United States had to be flown back to Asia for dicing, advanced packaging, and final testing. Nvidia’s agreement with Amkor aligns directly with a 10-year partnership between TSMC and Amkor, ensuring American-made silicon undergoes full turnkey packaging locally in Arizona.
Amkor is rapidly scaling its physical footprint in Arizona to support the influx of demand from Nvidia and other major tech clients. Located within Peoria’s Innovation Core, Amkor originally broke ground on a 104-acre advanced packaging campus representing a $1.2 billion initial capital investment. To accommodate Nvidia’s multi-year capacity commitment, Amkor recently acquired an adjacent 67-acre land parcel, creating a 171-acre mega-site designed to become the largest outsourced semiconductor assembly and test facility in North America.
Executive leadership from both technology companies emphasized the strategic importance of building resilient domestic supply chains. Debora Shoquist, Executive Vice President of Operations at Nvidia, stated that artificial intelligence is driving a generational technology shift that requires revitalized American manufacturing. Amkor Chief Executive Officer Kevin Engel noted that the $1.5 billion partnership accelerates Amkor’s long-term technology roadmap while providing full turnkey packaging and test solutions for critical AI infrastructure.
The multi-billion-dollar deal aligns closely with broader industrial policy goals established under the United States CHIPS and Science Act. While federal incentives encouraged foundry operators like TSMC, Intel, and Samsung to construct domestic wafer fabs, government officials and defense leaders warned that relying on overseas packaging plants left the technology supply chain vulnerable to geopolitical disruptions. Establishing advanced packaging lines in Arizona ensures that defense contractors and cloud operators can procure completely domestic AI chips.
Global demand for artificial intelligence hardware has severely strained traditional packaging capacity across East Asia over the past three years. Major cloud providers—including Microsoft, Amazon, Google, and Meta—have faced delivery delays for AI server racks due to limited capacity for Chip-on-Wafer-on-Substrate packaging. By expanding domestic assembly lines with Amkor, Nvidia is diversifying its packaging supplier base beyond traditional Taiwanese packaging facilities, ensuring higher delivery volumes for global cloud data centers.
Nvidia’s $1.5 billion investment in Amkor marks a transformative milestone for North American semiconductor manufacturing. As artificial intelligence models expand toward multi-trillion-parameter architectures, the semiconductor industry relies increasingly on advanced chiplet integration rather than traditional single-die chips. By uniting front-end wafer fabrication with state-of-the-art back-end packaging in Arizona, Nvidia and Amkor are establishing a robust, geographically diverse hardware ecosystem capable of powering the global AI revolution for the next decade.
