Fortifying domestic supply chain resilience:
Amkor’s commitment to a robust American semiconductor ecosystem

The establishment of Amkor’s next factory in Arizona stems from the US CHIPS Act initiative to strengthen domestic semiconductor supply chains. After evaluating multiple states, we selected Peoria, Arizona, due to its strategic advantages, including proximity to TSMC (the world’s largest silicon foundry). This location enables us to create a robust ecosystem alongside TSMC, Intel, and other industry leaders, leveraging shared educational resources, supplier networks, and technical services.

Amkor Technology Arizona and green manufacturing

Our stated ESG mission is to pursue agile and dependable manufacturing that drives sustainable practices, aligns with our core values of reliability and trust and maintains our commitments to our communities, customers, suppliers, employees, business partners and shareholders.

Net Zero Goal

At Amkor Technology, we are deeply committed to the communities we serve and the environment we share. By adhering to the Science Based Targets initiative (SBTi), we have established ambitious, verified goals that demonstrate our dedication to sustainable manufacturing. We’re actively working to reduce our absolute Scope 1 and 2 greenhouse gas emissions by 55% by 2030, with an ultimate target of achieving net zero emissions by 2050.

Our environmental strategy aligns with leading industry standards through our participation in the Responsible Business Alliance, and Responsible Mineral Initiative, and compliance with Sustainability Accounting Standards Board guidelines. Beyond emissions, we’ve set concrete goals to reduce water usage and waste generation by 20% by 2030, and we proudly support the City of Peoria’s initiatives to maximize water reclamation. These science-based commitments reflect our holistic approach to environmental stewardship and our responsibility to both our local community and the global ecosystem. Discover more about our ESG mission!

Water Management

At our new Peoria facility, Amkor is implementing comprehensive water management strategies that reflect our deep commitment to environmental stewardship and community responsibility. We’ve designed our operations to limit water consumption to a maximum of 1.9 million gallons per day, with at least 80% coming from reclaimed sources. Our facility will feature a state-of-the-art industrial wastewater pretreatment program that adheres to all federal, state, and municipal requirements, building on our extensive experience with wastewater management across our global operations.

We’re investing in advanced purification systems that enable us to use reclaimed water in our semiconductor assembly processes, demonstrating our dedication to conservation in water-sensitive Arizona. Furthermore, we’ve established a collaborative partnership with the City of Peoria to continuously improve wastewater processing techniques, ensuring that water can be effectively recycled within our operations. This approach not only minimizes our environmental footprint but also supports the long-term sustainability of water resources in the community we’re proud to join.

Noise Management

Amkor is committed to being a good neighbor to Peoria residents through responsible noise management at our new facility. While Peoria city code permits sound levels up to 80 dBA during daytime hours (6:00 AM-10:00 PM) and 70 dBA overnight (10:00 PM-6:00 AM) when measured at property boundaries, we’re setting a much higher standard. Based on measurements from our largest existing facility, which registers only 44-59 dB—significantly below local requirements—residents can expect minimal noise disruption from our operations.

This careful attention to sound levels demonstrates our respect for the community’s quality of life and our dedication to creating a manufacturing environment that harmoniously coexists with surrounding neighborhoods. Our proactive approach to noise mitigation reflects Amkor’s broader commitment to responsible corporate citizenship and environmental stewardship in all the communities where we operate.

Career opportunities

As one of the most important semiconductor packaging pioneers and the leader in the OSAT (Outsourced Semiconductor Assembly and Test) market, Amkor is relied on by the world’s biggest semiconductor companies to bring their designs to completion. We are seeking top talent to join our Arizona team, where innovation and manufacturing excellence converge in America’s semiconductor corridor.
