Amkor Technology Korea (Amkor) held a groundbreaking ceremony for the expansion of its Gwangju plant in Buk-gu, Gwangju, on the morning of October 19.


As part of a mega semiconductor project in the southwestern region, Amkor plans to invest a total of 3 trillion won by 2031 to enhance its advanced packaging production facilities for artificial intelligence (AI) and high-performance computing (HPC).


The investment amount has been increased by 2 trillion won compared to initial plans, and the timeline for the investment has been accelerated.


This initiative is expected to create significant synergy with Samsung Electronics and SK Hynix, which are investing 800 trillion won to build advanced semiconductor manufacturing plants in the Gwangju area.


Attendees at the groundbreaking ceremony included Lee Min-woo, Director of the Industrial Growth Division at the Ministry of Trade, Industry and Energy; Gwangju Mayor Min Hyung-bae; Amkor's headquarters executives; and representatives from global clients.


In response to the growing demand for advanced packaging, Amkor plans to invest a total of 3 trillion won and hire over 2,000 new employees by 2031.


The new facility will produce advanced packaging products for AI data centers and supercomputers.


Two buildings are expected to be completed in the second half of 2027, with an additional two buildings slated for completion in the first half of 2028, leading to mass production.


Advanced packaging technology enhances performance and energy efficiency by stacking or connecting different semiconductor chips.


As semiconductor circuit miniaturization approaches physical limits, this technology is becoming increasingly important for the performance of AI semiconductors.


The Gwangju Metropolitan City expects that the expansion of Amkor's Gwangju plant will mark a transition from planning to actual investment and construction in the government's initiative to establish a semiconductor ecosystem in the southwestern region.


Headquartered in the United States, Amkor Technology is a leading provider of advanced semiconductor packaging and foundry services for back-end testing (OSAT). The company operates more than 20 facilities across eight countries.


In South Korea, Amkor has three plants located in Songdo, Bupyeong, and Gwangju. Last year, the company employed over 8,400 people and generated annual revenue of approximately 5 trillion won.
