Amkor Technology Acquires 67 Additional Acres in Arizona, Expanding U.S. Advanced Packaging Footprint

Dataquest Bureau USA

Overview

Amkor Technology has secured an additional 67 acres adjacent to its existing campus in Peoria, Arizona, to significantly expand its U.S. advanced semiconductor packaging and test capabilities. This strategic move aims to support large-scale, cutting-edge operations for the AI, high-performance computing, automotive, and communications markets. The expansion is anticipated to become the first high-volume advanced packaging OSAT facility in the U.S., directly addressing the domestic chip production trend and surging demand for AI-centric semiconductor services.

In Depth

Key Findings

Amkor Technology has bolstered its commitment to expanding advanced semiconductor packaging and test capabilities in the United States by securing an additional 67 acres of land adjacent to its existing manufacturing campus in Peoria, Arizona. This strategic expansion is designed to address the surging demand from the artificial intelligence (AI), high-performance computing (HPC), automotive, and communications markets, as well as to align with U.S. policies aimed at strengthening domestic semiconductor manufacturing.

Technical Details

The land acquisition provides Amkor with strategic flexibility for future expansions of its advanced packaging and test facilities in Arizona. The company’s Peoria plant already offers a comprehensive range of packaging solutions, including wafer bump, wafer test, flip chip, and System-in-Package (SiP) technologies. This expansion will enable Amkor to further increase its production capacity for high-density, power-efficient advanced packaging technologies, which are essential for AI chips and HPC processors. This is crucial for enabling more complex heterogeneous integration and chiplet-based designs.

Background and Context

The explosive growth of AI demand is accelerating investments in advanced semiconductor packaging worldwide. In the U.S., in particular, policies such as the CHIPS Act are driving the reinforcement of domestic manufacturing capabilities. Amkor’s investment aligns with the broader trend of U.S.-based companies seeking to build more resilient semiconductor supply chains and mitigate geopolitical risks. This facility is expected to become the first high-volume advanced packaging OSAT (Outsourced Semiconductor Assembly and Test) facility in the U.S., playing a critical role in strengthening the domestic chip production ecosystem.

Strategic Significance and Outlook

Amkor’s Arizona expansion is vital for alleviating advanced packaging bottlenecks within the U.S. semiconductor supply chain and stabilizing the domestic supply of chips for the AI, HPC, and automotive markets. This facility will serve as a core hub to meet the robust demand for advanced packaging, which is projected to continue beyond 2027. It is expected to significantly contribute to strengthening the competitiveness and accelerating innovation within the U.S. semiconductor industry, while also creating new employment opportunities.
