South Korea recently officially unveiled its national AI semiconductor development strategy, marking a new phase in global memory chip competition. Samsung Electronics and SK Hynix, the two leaders in the global memory chip industry, have confirmed a combined local investment of approximately 2,000 trillion Korean won over the next decade, equivalent to about $1.3 trillion. This epic funding will focus on High Bandwidth Memory (HBM), advanced wafer manufacturing, and AI computing infrastructure. The aim is to reshape the competitive landscape of the global semiconductor supply chain by expanding upstream storage capacity.
The investment plan is integrated into South Korea's national industrial strategy, with semiconductors, embodied AI, and large AI data centers listed as the three core pillars of the national economy. The core objective is to double Dynamic Random Access Memory (DRAM) capacity within five years, consolidating South Korea's dominance in the AI HBM field. Capital allocation tilts towards computing-heavy sectors. Approximately 800 trillion won will be used to build multiple advanced wafer factories in Gwangju and Yongin to increase mass production capacity for next-generation storage chips. Another 81 trillion won will be allocated to advanced HBM packaging lines in the Chungcheong region to address shortcomings in AI chip packaging. Remaining funds will go towards building large domestic intelligent computing centers, supporting infrastructure like power, water, and land. The government promises comprehensive policy support to significantly accelerate fab construction, expecting production to start 7 to 12 years ahead of schedule.
At the corporate level, Samsung Group announced a comprehensive investment plan, with most funds dedicated to the semiconductor sector. Gwangju is selected as the new wafer manufacturing base with plans for multiple modern fab buildings, while mature industrial clusters in Yongin and Pyeongtaek will be upgraded, focusing on storage chips urgently needed for AI servers. SK Group is also synchronizing with hundreds of billions of won in supporting investment to accelerate the Yongin semiconductor cluster launch and advance next-generation storage R&D. Both companies are focused on high-end storage capacity expansion, directly facing competitive pressure from logic chip manufacturing and overseas industrial policies.
International financial institutions quickly analyzed that this plan will directly push global memory chips into a cycle of rising volume and prices. Coupled with recent trends of concentrated price hikes by global semiconductor manufacturers, prices for power chips and Multi-Layer Ceramic Capacitors (MLCC) have risen significantly. Downstream servers, consumer electronics, and new energy vehicle companies will continue to bear upward cost pressure. Geopolitically, given the US is re-reviewing overseas subsidies under the CHIPS Act, the subsidy prospects for Samsung and SK Hynix building fabs in the US remain uncertain. Boosting domestic capacity is also a key strategy for Korean firms to hedge against overseas policy risks.
Industry analysis points out that South Korea's long-term investment scale is huge, representing the largest single-country private semiconductor investment plan to date. In the short term, this will boost the prosperity of the Japan-Korea semiconductor equipment and material supply chains. In the mid-to-long term, it will exacerbate differentiation in the global chip sector. Korean firms' influence in the storage sector will be further strengthened. This will force China, the US, and Europe to accelerate autonomous construction of local computing storage supply chains. The regionalization competition of the global AI chip supply chain will usher in a new development stage.
