Amkor breaks ground on $7 billion advanced manufacturing facility in Peoria

PHOENIX — Amkor Technology has broken ground on a $7 billion advanced manufacturing campus in northern Peoria.

City officials gathered at the construction site just off Lake Pleasant Parkway, near Loop 303, on Monday.

Gov. Katie Hobbs believes the advanced manufacturing campus will put Arizona at the center of artificial intelligence (AI) development.

“This will be the largest outsourced packaging plant in North America, expected to bring 3,000 jobs here to Peoria,” she said at the event. “It will enable us to test and package more chips.”

Officials with the company, a global leader in semiconductor packaging and testing, expect the site to be fully operational in 2028.

Details about Amkor Peoria advanced manufacturing campus

The Amkor Peoria campus will feature over 750,000 square feet of cleanroom manufacturing space, according to the company. It will package and test chips for Apple.

The company originally invested $2 billion into the project but added another $5 billion this week, announced shortly before a ceremonial groundbreaking.

Peoria Mayor Jason Beck and Amkor officials credited TSMC’s investment and fabrication center in Phoenix as a factor that drove this project forward.

“Prouder than proud to have Amkor do what they’re doing and really make this historic investment,” Beck said at the event.

He hopes this will spur the city’s Big Tech presence, as it is the first business to build within Peoria’s new Innovation Core.

Amkor Peoria campus had a rocky road leading up to construction

For years, Amkor has eyed land in Peoria to build the advanced manufacturing campus.

An original site the chip maker had planned to build out was right in a Peoria master-planned community known as Vistancia.

Mike Kelleher with Citizens for Smart Growth, a community of residents in Vistancia, opposed Amkor’s original site near their neighborhood.

“People have made choices … bought forever homes … and they’re putting 2.7 million-square-foot factory in the middle of it,” Kelleher told KTAR News 92.3 FM in April.

He was happy with Amkor’s decision to move the project to a 104-acre patch of land in Peoria.

“I think it’s a win-win,” Kelleher told KTAR News 92.3 FM after the Monday groundbreaking.

This way, innovation won’t disrupt residents’ daily lives, he added.
