Amkor Technology has snapped up a 67-acre parcel next to its under-construction campus inside Peoria’s Innovation Core, giving the advanced semiconductor packaging and test complex going up north of Loop 303 a lot more elbow room. The extra land is meant to keep pace with surging demand for AI and high-performance chip packaging.
The company confirmed the land deal in a press release, noting that the new parcel sits beside the 104-acre site already designated for its Arizona campus and “provides strategic flexibility to support future expansion and evolving customer demand.” In that same statement, Amkor said the added acreage is meant to help the company respond as customer needs shift during the campus buildout.

Campus size, timeline and jobs
The project has already bulked up since it was first unveiled. Amkor has outlined plans for roughly a $7 billion investment that would include more than 750,000 square feet of cleanroom manufacturing space and as many as 3,000 jobs once the site is fully built out, according to earlier company announcements. That is a lot of white suits by any measure.
Local reporting and planning documents describe the overall campus as a roughly 2.3 million square foot buildout across two phases, with the first phase targeted for completion in mid-2027 and production expected to start in early 2028. InBusiness PHX.
Local planning and the Innovation Core
The land purchase follows a run of city actions to assemble and master-plan the Peoria Innovation Core, where officials have been putting in backbone infrastructure to pull in suppliers and supporting industries. City economic development materials show Amkor’s site ringed by newly planned roads and utilities, and nearby parcels, including a 12.2-acre tract at the northeast corner of Amkor Way and 96th Avenue, are being marketed to vendors and speculative industrial developers that would serve the campus.

Analysts and local leaders say the additional acreage gives Amkor room to grow close to front-end fabs and key customers, which could shorten the packaging supply chain and keep more work onshore. The company has also sought federal support tied to the CHIPS Act and other incentives connected to the project, details it has previously laid out in filings and news releases that discuss proposed CHIPS funding and related tax credits.

For Peoria, the new land deal reinforces the city’s role in the national effort to pull more of the semiconductor supply chain back to the United States and hints at a longer runway for construction, supplier recruitment and jobs across the West Valley. Local coverage has tracked the sale and the city’s push to position nearby industrial parcels for companies that want to land close to Amkor and other chip players circling the area.
