SK Hynix has announced its decision to inject an additional 21.6081 trillion KRW (approximately 103.978 billion RMB) into Phase 1 of its Yongin Semiconductor Plant in Gyeonggi Province, with the investment period running through the end of 2030.
SK Hynix stated that the company has determined that with the rapid evolution and proliferation of AI, global demand for memory is concentrating on its products, requiring aggressive expansion of production infrastructure to accommodate growth. The plant will serve as a manufacturing base for High Bandwidth Memory (HBM), the core memory chip for AI applications.

The company approved the large-scale additional facility investment through a board resolution on the same day and made the announcement. Including the approximately 9.4 trillion KRW facility investment announced in July 2024, the total investment for Phase 1 now amounts to roughly 31 trillion KRW (approximately 149.172 billion RMB).
Explaining the reason for the additional investment, the company noted:“With the expansion of advanced industries such as AI, data centers, and high-performance computing, demand for high-performance, high-integration semiconductors is expanding structurally. To adapt to this shift, the company will expand production capacity in advance and establish a foundation for stable product supply at the time required by customers.”
The additional investment will be used to complete the main structure construction of Phase 1 and build all clean rooms from Building 2 (Phase 2) to Building 6 within the plant.Phase 1 is an ultra-large-scale complex consisting of 2 main structures and 6 clean rooms.

Furthermore, SK Hynix expects to advance the clean room completion date from May next year to February, three months earlier than originally planned, meaning the plant is on track for early production.
A company official stated:“We will establish a practical operating system in a timely manner according to the early production preparation progress to ensure flexible response to future demand.”“Based on large-scale investments, SK Hynix will continue to expand production capacity, strengthen trust with customers, and solidify its leading position in the global semiconductor market.”
Meanwhile, the company added:“Taking this investment as an opportunity, SK Hynix will accelerate the development of a co-prosperity ecosystem with around 50 partner companies in the cluster.” It also stated: “The company will work closely with materials, components, and equipment companies to drive mutual growth through expanded production capacity, and build a world-class semiconductor cluster that leads not only in Korea but also globally through synergies.”
