Amkor Announces New Arizona Facility for Advanced Semiconductor Packaging and Test Services.

Amkor Technology plans to build a new semiconductor advanced packaging and test facility in Arizona. The 104-acre site in the Peoria Innovation Core will be constructed within days, with production expected to start in early 2028. The facility will bring a $2 billion investment and 2,000 new jobs to the community. Amkor has operated in the Greater Phoenix area since 1984 and will work with TSMC and other key semiconductor companies to provide advanced manufacturing for industries such as computing, communications, and automotive.

Amkor Technology, Inc. (Nasdaq: AMKR), a leading provider of semiconductor packaging and test services, has announced plans to build a new advanced packaging and test facility in Peoria, Arizona. The 104-acre site within the Peoria Innovation Core (PIC) is set to begin construction within days, with production expected to commence in early 2028 [2].

The facility will bring a significant investment to the community, with a projected $2 billion investment and the creation of 2,000 new jobs [1]. Amkor has operated in the Greater Phoenix area since 1984 and is committed to strengthening the U.S. semiconductor supply chain [3].

The city of Peoria approved a land swap and an amended development agreement, allowing Amkor to exchange its previously designated 56-acre parcel within the Five North at Vistancia community for the new 104-acre site in Core 2 [1]. The city is leading the master planning for the PIC, which includes 7,000 acres of land and aims to catalyze economic development [1].

Amkor will work with key semiconductor companies, such as TSMC, to provide advanced manufacturing for industries such as computing, communications, and automotive [2]. The new facility will reinforce Amkor's commitment to U.S.-based chip manufacturing and meet growing customer demand [3].

The city of Peoria is excited about the potential economic growth and job creation that Amkor's new facility will bring. Mayor Jason Beck stated, "Today represents a historic milestone for the partnership between the City of Peoria and Amkor. By securing this land, we are not only bringing a $2 billion investment and 2,000 new jobs to our community, but we are further solidifying the important role Peoria will play in strengthening America’s critical semiconductor supply chain" [1].

The construction of the facility is expected to be completed in two phases, with the first phase consisting of a processing facility and several ancillary structures, and is anticipated to open in late 2027 [1].
