Semiconductor Packaging Market Draws US$12 Billion Amkor Expansion in Arizona

Amkor Technology announced a second phase for its Arizona advanced packaging and test campus, raising the planned investment to US$12 billion. The expansion is set to add 60,000 square meters of cleanroom space, taking the campus to about 93,000 square meters, after customer commitments exceeded the capacity planned for the first phase. The project will expand U.S. packaging capacity for complex chips used in AI, high-performance computing, mobile communications and automotive systems.

Amkor, ASE, TSMC, Samsung and JCET are among the companies positioned to benefit from rising demand for advanced assembly, testing and heterogeneous integration. Capacity additions create opportunities for equipment, substrate and materials suppliers, as well as partnerships between chip designers and packaging providers. With customers seeking qualified capacity near U.S. chip production, Asian OSAT leaders may face pressure to expand geographically and compete on delivery timelines, technology and supply-chain resilience.

According to DataM Intelligence, the global Semiconductor Packaging Market reached US$76.86 billion in 2025 and is projected to reach US$144.18 billion by 2033, growing at a 7.6% CAGR from 2026 to 2033.

Asia-Pacific accounts for about 58% of the market and remains the fastest-growing region, supported by established packaging and testing hubs in Taiwan, China and South Korea. AI and high-performance computing are increasing demand for 2.5D and 3D integration, chiplets and high-bandwidth memory packaging. Amkor's U.S. expansion and ASE's NT$17.8 billion Taiwan project illustrate how suppliers are adding advanced packaging and testing capacity to serve these applications closer to major customers.

Market scope spans technologies, materials and end users

DataM Intelligence segments the semiconductor packaging market by technology, including grid-array, small-outline, flat no-leads and dual in-line packaging; by material, including plastic, ceramic and metals; and by end user, including consumer electronics, automotive, healthcare, IT and telecommunications, and aerospace and defense. These segments serve different requirements for cost, thermal performance, reliability, footprint and production volume.

Consumer electronics demand supports high-volume packaging across devices such as smartphones, computers and wearables. Automotive applications place greater emphasis on long-term reliability and operating conditions, while data-center and AI workloads are increasing interest in packages that support high-speed connections and tighter integration. For semiconductor manufacturers and outsourced semiconductor assembly and test providers, choosing a package involves balancing design requirements with materials availability, manufacturing yield, qualification time and total cost.

The report identifies Asia-Pacific as a major center of the packaging ecosystem, estimating that the region accounted for around 58% of market share in 2025. Its concentration of foundries and outsourced assembly and test capacity supports its position across established and advanced packaging. North America and Europe also represent significant markets, with investment priorities shaped by supply-chain resilience, automotive electronics and efforts to expand local manufacturing capabilities.

Recent agreements and investments target capacity and collaboration

Recent announcements show how companies are responding to packaging demand through capacity expansion and ecosystem partnerships. In September 2026, Amkor Technology announced a second phase for its Arizona advanced packaging and test campus. The company said the expansion is expected to add 60,000 square meters of cleanroom space and bring its planned total investment in the campus to US$12 billion. Construction of the second phase is anticipated to begin in late 2027, with completion expected by the end of 2029. The timeline and capacity remain subject to project execution.

In September, Tata Electronics and Dutch equipment supplier Besi signed a memorandum of understanding to strengthen advanced packaging capabilities in India. The collaboration is intended to support technology readiness, equipment capabilities, engineering development and training at Tata Electronics' planned semiconductor packaging facility in Jagiroad, Assam. The agreement illustrates how equipment access and technical expertise are part of building packaging operations, alongside investment in production facilities.

In July 2026, Samsung Electronics and Broadcom announced an expanded collaboration spanning memory, foundry and advanced packaging for AI infrastructure. The companies said their work would include advanced packaging based on Samsung's 2-nanometer process, including 2.3D and 2.5D integration. The companies described the broader collaboration as an expected opportunity of more than US$200 billion across memory and foundry through 2030; that figure refers to the collaboration across those areas, not to semiconductor packaging alone.

Together, the announcements point to different routes for developing the sector: adding manufacturing space, building local technical capabilities and coordinating packaging with memory and foundry roadmaps. Announced investments and agreements are not the same as available production capacity. For buyers, deployment will depend on construction and qualification schedules, customer commitments, process yields and the ability to deliver consistent package performance at scale.

Qualification, capacity and cost will shape adoption

Companies evaluating packaging suppliers need to consider the full production pathway: package design, materials, assembly equipment, thermal and electrical performance, testing, manufacturing yield and capacity access. A technically suitable package may still face delays if it is difficult to qualify, relies on constrained materials or cannot be produced at the required volume. High capital requirements and specialized expertise also influence how quickly new facilities and processes can reach commercial production.

DataM Intelligence's report provides market sizing and forecasts through 2033, alongside analysis by technology, material, end user and region. It is designed to support semiconductor manufacturers, foundries, outsourced assembly and test providers, equipment and materials suppliers, electronics companies, investors and procurement teams assessing packaging strategies, capacity plans and market opportunities.
