Samsung, SK Hynix Eye Honam Region in South Korea for First Advanced Packaging Fabs Amid Soaring AI Memory Demand; Amkor Plans $980M Expansion

The Elec Inc. South Korea

Overview

Samsung Electronics and SK Hynix are considering establishing their first advanced semiconductor packaging plants in South Korea’s Honam region to meet surging AI infrastructure demand. Samsung is weighing Gwangju and Saemangeum, while SK Hynix is looking at Gwangju or Muan as potential sites. This move is complemented by Amkor Technology’s existing Gwangju ecosystem, with Amkor planning a $980 million investment by 2035 to add 1,000 jobs, addressing HBM packaging capacity shortages and aligning with government regional development policies.

In Depth

Key Findings

Samsung Electronics and SK Hynix are actively exploring the establishment of new advanced semiconductor packaging (back-end) facilities in South Korea’s Honam region. This strategic initiative aims to address the explosive growth in AI infrastructure demand, particularly for high-bandwidth memory (HBM), and to bolster the companies’ competitive edge in the global semiconductor supply chain. The Honam region, including Gwangju, already benefits from an established ecosystem of outsourced semiconductor assembly and test (OSAT) providers like Amkor Technology, which itself plans to invest approximately $980 million in its Gwangju plant by 2035, creating 1,000 new jobs.

Technical & Economic Details

Samsung is considering Gwangju and Saemangeum, while SK Hynix is evaluating Gwangju or Muan as potential locations for their new packaging facilities. While official investment figures remain undisclosed, the combined investment is projected to be in the realm of $1 billion. The Honam region’s appeal stems from its advantageous infrastructure, including relatively affordable land, abundant water resources crucial for semiconductor manufacturing, and stable power supply. Leveraging Amkor’s existing presence, these new investments are expected to significantly strengthen the regional semiconductor industry cluster, fostering synergies and technological advancements.

Background & Context

Advanced packaging technologies, such as those integrating logic and HBM chips, are critical enablers for next-generation AI processors. Currently, packaging capacity, particularly TSMC’s CoWoS, represents a significant bottleneck in AI chip supply chains globally, driving urgent expansion efforts across the industry. The South Korean government’s policy of balanced regional development also plays a role, as these investments align with national objectives to distribute industrial growth beyond traditional hubs. This domestic expansion is anticipated to enhance the resilience of Korea’s semiconductor ecosystem against external supply chain disruptions.

Outlook

The realization of these investments in the Honam region would solidify South Korea’s leadership in the AI semiconductor market. The expanded packaging capacity, coupled with Amkor’s contributions, will be vital for accelerating global AI infrastructure build-out. Economically, the initiative is poised to generate substantial employment opportunities and attract ancillary industries to the region. Furthermore, the focus on leveraging local infrastructure, including potential for renewable energy, hints at a broader commitment to sustainable manufacturing practices within the advanced packaging sector.
