Apple has announced a partnership deal with Amkor, one of the leading chip packaging and testing manufacturers, which will build a two billion US Dollar silicon packaging facility in Peoria, Arizona. Being the only US-based OSAT (outsourced semiconductor assembly and test) provider, Amkor has decided to invest its funds and apply for the CHIPS Act, hoping to get a part of the funding from the US government's grant budget. The state-of-the-art facility in Arizona will feature over 500,000 square feet (46,452 square meters) of cleanroom space for packaging and testing chips. Using Amkor's latest technologies, the plant will support advanced computing, automotive, and communications chip packaging. It is tailored to meet the capacity needs of major customer Apple starting in 2025-2026. Apple will be the largest customer, with the Amkor facility packaging Apple-designed chips produced at the nearby TSMC wafer fabrication plant.

Building a chip packaging facility in the US with advanced packaging types means that the domestic manufacturing of advanced silicon is now possible across almost the entire supply chain, with OSAT now being present on US soil as well. In the initial phase, this partnership will enable domestic advanced packaging capabilities for leading-edge chips down to 3 nm nodes, which Apple plans to utilize for its A and M series of processors. Along with the creation of an estimated 2,000 local jobs, the investment serves as a boost to the local economy as well. Additionally, Amkor is TSMC's strategic partner, meaning future designs and packaging will cooperate without any delays.
