In a major move for U.S. semiconductor manufacturing, Amkor Technology has officially broken ground on a new advanced semiconductor packaging and test campus in Peoria, Arizona. The investment, estimated at $7 billion and expected to create up to 3,000 jobs, marks a major step in reshoring critical parts of the chip supply chain back to the United States.

In this article, we will explain what’s happening, why it matters, what the implications are, and what to watch next — all in clear, accessible language.
What’s happening: Key details of the investment
-
Amkor Technology’s new campus is located in Peoria, Arizona and is described as an advanced packaging and test facility, with clean-room space up to 750,000 square feet in its full scope. (Tom's Hardware)
-
The investment has expanded from an earlier estimate of about $2 billion to roughly $7 billion across two phases. (Construction Dive)
-
Construction is expected to be largely completed by mid-2027 with production beginning in early 2028. (Manufacturing Dive)
-
The facility will support advanced packaging technologies for major customers including Apple Inc. and Nvidia Corporation, and will complement adjacent wafer-fab operations in Arizona. (Tom's Hardware)
-
The project benefits from federal support under the CHIPS Act and state/local incentives, reflecting its strategic importance. (Construction Dive)
Why this matters: Strategic implications for U.S. tech & manufacturing
1. Closing a major gap in the U.S. chip supply chain
While much attention is paid to wafer fabrication (the “front end”), packaging and testing are often known as the “back end” of the semiconductor supply chain. Many of these operations are currently located overseas, especially in Asia. Amkor’s new campus is a step toward bringing that capability back to the U.S. (Tom's Hardware)
2. Strengthening domestic resilience and sovereignty
By investing in packaging and test capacity domestically, the U.S. is reducing its dependence on foreign supply-chains. This is important not just for economic competitiveness, but also for national security in a world where semiconductors are critical. (Expansion Solutions)
3. High-tech jobs and regional economic boost
The creation of thousands of jobs in Arizona — in advanced manufacturing, engineering, operations — could bring major economic benefits to the region. It also signals that high-tech manufacturing is returning to U.S. soil in meaningful ways. (Manufacturing Dive)
4. Alignment with AI, HPC, automotive trends
The packaging technologies being targeted are not just generic; they are designed to handle advanced chips used in artificial intelligence, high performance computing (HPC), automotive, mobile communications. These are growth areas. (Tom's Hardware)
What are the implications for stakeholders?
-
For Amkor Technology: This campus positions it as a leading U.S.-based advanced packaging partner. It can win more business from major fab operators and tech companies seeking U.S. supply-chain solutions.
-
For fabs and chipmakers: Foundries like Taiwan Semiconductor Manufacturing Company (TSMC) and others that build wafers may gain from more local packaging capacity — reducing logistics, lead-times, and risk. According to sources, Amkor’s site is meant to complement TSMC’s nearby wafer fabs. (Tom's Hardware)
-
For the U.S. economy and policy makers: The project supports domestic manufacturing goals and may help catalyse further investments in the semiconductor ecosystem.
-
For the workforce: New jobs in a high-tech manufacturing field may lead to more training, skill-development and opportunities in Arizona and the broader U.S.
Risks and challenges to keep in mind
-
Timeline and execution: While the project is ambitious, it still faces the usual risks of large construction and manufacturing projects — delays, cost overruns, regulatory issues, workforce shortages. For instance, production begins in early 2028, which means benefits won’t accrue immediately. (Manufacturing Dive)
-
Workforce/skills availability: Advanced packaging requires skilled workers, clean-room operations, high-precision manufacturing. The U.S. has had challenges building this talent pool quickly.
-
Global competition: The U.S. is making major moves, but so are other countries — Asia, Europe — in semiconductor manufacturing. To maintain competitiveness, cost structure, technology, and scale all matter.
-
Technology risk: Packaging is rapidly evolving (2.5D, 3D stacking, heterogeneous integration). The facility must stay ahead of the curve to serve high-end markets.
-
Integration and ecosystem: The facility’s success may depend on how well it aligns with upstream wafer fabs, downstream assembly/test, and customers. If the broader ecosystem is slow to develop, bottlenecks may persist.
What to watch going forward
-
Progress milestones: Watch for announcements of facility completion phases (mid-2027) and first production (early 2028).
-
Customer sign-ups and partnerships: How many major chip-makers commit to using the facility? What are the types of chips/processes targeted?
-
Technology deployment: Which advanced packaging technologies will be used (e.g., 2.5D, CoWoS, heterogeneous integration)?
-
Workforce and training programmes: Are local universities, community colleges participating? How many jobs fill and what skill levels?
-
Economic and supply-chain impact: Will shipments begin from this facility? Will other firms announce complementary facilities (e.g., test, materials, equipment) nearby?
-
Policy/regulatory support: Will further federal or state incentives be offered? Will export controls, tariffs or trade policy affect the ecosystem?
-
Regional impact in Arizona: How will this project affect Arizona’s status as a semiconductor hub (alongside TSMC and others)?
Simple summary for everyday readers
Here’s a boiled-down version in plain English: A major tech manufacturing company, Amkor Technology, is building a huge new campus in Arizona to do the final steps of making advanced chips — packaging and testing them. They plan to spend up to $7 billion, create thousands of jobs, and target the cutting-edge chips used in AI, cars and high-power computing. The facility isn’t just next year’s news — it starts production in 2028 — but it’s a big deal because it helps bring critical parts of the chip-industry back to the U.S. instead of abroad. There are challenges ahead, but the mission is clear.
Final thoughts
The focus keyword “Amkor Technology Arizona campus” captures the essence: Amkor’s move to build a major packaging and test facility in Arizona is both a business play and a strategic signal. It says the U.S. is serious about closing supply-chain gaps in semiconductors and bringing manufacturing back home.
For investors, aerospace/defence watchers, tech industry analysts, and policy-followers alike, this project is a milestone. It isn’t just about one facility — it is about a shift in how we think of manufacturing, technology, and national competitiveness.
If Amkor executes well, the campus could become a key node in the U.S. semiconductor ecosystem. If delays or cost issues emerge, it will serve as a reminder of how hard shifting global manufacturing can be. For now, the shine is bright and the ambition is bold.
As always, I recommend keeping an eye on the updates every six months or so — when construction advances, when customers sign, when the first chips roll out. Because this is not just “another factory” — it could be a cornerstone for the next decade of U.S. tech manufacturing.
