SK hynix is expanding its domestic manufacturing capabilities to keep pace with the rapid growth of the artificial intelligence (AI) market. As demand for high-performance memory products, particularly High Bandwidth Memory (HBM), continues to rise, the company is accelerating investments to strengthen its production infrastructure.

Nearly KRW 7.09 Trillion Investment in the Cheongju P&T7 Facility

On July 22, SK hynix announced through a regulatory filing that it will invest approximately KRW 7.09 trillion in the construction of its Cheongju P&T7 production facility.

According to the filing, the investment period will run from November 2025 through the end of 2032. The investment represents approximately 5.88% of the company's shareholders' equity.

SK hynix stated that the primary objective of the investment is to secure additional production capacity to meet the growing global demand for AI memory products.

Strengthening HBM Manufacturing Capabilities

The rapid expansion of generative AI applications and AI data centers has significantly increased demand for High Bandwidth Memory (HBM), one of the most important components used in AI accelerators.

HBM consists of multiple DRAM chips stacked vertically using advanced packaging technology, making its manufacturing process more complex than that of conventional memory products.

As a result, not only wafer fabrication but also packaging and testing capabilities have become critical competitive advantages in the AI memory industry.

What Is the P&T7 Facility?

The Cheongju P&T7 facility will focus on the packaging and testing processes for memory semiconductors.

Packaging and testing are essential final stages of semiconductor manufacturing, ensuring both product performance and quality before shipment.

With demand for AI memory products continuing to grow, expanding advanced packaging capacity has become an increasingly important strategic priority for semiconductor manufacturers.

Investment Schedule Adjusted, Overall Plan Unchanged

SK hynix explained that the latest announcement does not represent a change in its overall investment strategy.

According to the company, the board approved a revised investment amount because the construction schedule—particularly the cleanroom opening timeline—has been accelerated.

The company also emphasized that the previously announced total investment plan of approximately KRW 19 trillion for the P&T7 project remains unchanged.

Preparing for Long-Term Growth in the AI Era

Global technology companies continue to expand investments in AI infrastructure, driving sustained demand for HBM and other advanced memory products.

To respond to these market trends, SK hynix is steadily increasing both production capacity and advanced semiconductor packaging capabilities.

The latest investment is expected to strengthen the company's long-term competitiveness in supplying high-value AI memory products as the global AI industry continues to expand.
