By GlobalDataLocated in Arizona’s high-tech corridor, the site will focus on advanced packaging and testing, forming part of a wider effort to develop US semiconductor infrastructure.
The campus is designed to incorporate smart factory technologies and scalable production lines tailored to requirements in AI, computing, mobile communications, and automotive industries.
In addition, the new facilities are expected to complement TSMC’s wafer manufacturing operations by providing downstream processing for complete semiconductor production.
The facilities are intended to serve major customers such as Apple and Nvidia.
Nvidia founder and CEO Jensen Huang said: “AI has ignited a new industrial revolution — and with it, the chance to reindustrialise America. Amkor’s new Arizona facility is a defining milestone in bringing this capability home.
“Together, we are rebuilding the supply chain — onshoring the AI technology stack that turns energy into intelligence and secures America’s leadership for the AI century.”
Amkor’s expanded investment benefits from support through the Trump Administration’s CHIPS for America programme, the Advanced Manufacturing Investment Tax Credit initiative, and contributions from state and local authorities.
