SK hynix held a press conference unveiling its vision and strategy for the AI era today at its headquarters in Icheon, Gyeonggi Province, to share the details of its investment plans for the M15X fab in Cheongju and the Yongin Semiconductor Cluster in Korea and the advanced packaging facilities in Indiana, U.S.

The event, hosted by theChief Executive Officer Kwak Noh-Jung, three years before the May 2027 completion of the first fab in the Yongin Cluster, was attended by key executives including the Head of AI Infra Justin (Ju-Seon) Kim, Head of DRAM Development Kim Jonghwan, Head of the N-S Committee Ahn Hyun, Head of Manufacturing Technology Kim Yeongsik, Head of Package & Test Choi Woojin, Head of Corporate Strategy & Planning Ryu Byung Hoon, and the Chief Financial Officer Kim Woo Hyun.

The opening speech by Kwak was followed by Justin Kim’s presentation on the company’s vision for AI memory, Choi Woojin’s introduction to SK hynix’s core technology for HBM and the plan for the advanced packaging facilities in the U.S., and Kim Yeongsik’s sharing of the plans for the M15X fab and the facilities for the Yongin Cluster. A question-and-answer session also followed.

Below are the key messages from the presentations at the event.

  • Company has maintained technological leadership in various AI applications
  • In DRAM space, company mass producing HBM3E and modules with ultra-high capacity of more than 256 GB, while having commercialized world’s fastest LPDDR5T
  • Company a top provider of AI memory also in NAND space as sole supplier of QLC-based SSD of more than 60 TB
  • Development of next-generation products with improved performance underway
  • Company planning to introduce innovative memory such as HBM4, HBM4E, LPDDR6, 300 TB SSD, CXL Pooled Memory Solution, and Processing-In-Memory

Core Technology for HBM and Advanced Packaging Facilities in the U.S. by Choi Woojin

  • SK hynix’s proprietary MR-MUF is a core technology for HBM packaging
  • Views that MR-MUF will face technological challenges in higher stacking incorrect as seen in SK hynix’s successful mass production of 12-high HBM3 with Advanced MR-MUF technology
  • MR-MUF lowers pressure from chip stacking to 6% level, raises productivity by 4 times by shortening time required for process, while improving heat dissipation by 45% VS previous technology
  • Advanced MR-MUF recently introduced by SK hynix improves heat dissipation by 10% by adopting a new protective material, while maintaining existing advantages of MR-MUF
  • Advanced MR-MUF, which adopts high-temperature, low-pressure methodology known for excellent warpage control, an optimal solution for high stacking and development of technology to realize 16-high stacking underway
  • Company plans to adopt Advanced MR-MUF for realization of 16-high HBM4, while preemptively reviewing Hybrid Bonding technology
  • Separately, company announced last month a plan to build advanced packaging facilities for AI memory in West Lafayette, Indiana
  • Mass production of AI products such as next-generation HBM from Indiana fab to start in 2H 2028
  • Indiana is center of the Silicon Heartland, a semiconductor ecosystem centered in the Midwest
  • SK hynix to strengthen collaboration with customers, competitiveness in AI space from Indiana, while fostering talent through cooperation with R&D centers to contribute to future of AI industry

Investment Plans for M15X in Cheongju and Yongin Semiconductor Cluster by Kim Yeongsik

  • Company plans to build M15X fab in Cheongju, North Chungcheong Province, as a rapid rise in demand for AI memory requires capacity expansion before operation at Yongin Cluster starts
  • M15X, a two-story fab that accommodates various processes for HBM production including EUV, expected to maximize production efficiency thanks to adjacency to M15, which has been expanding TSV capacity
  • Construction of M15X has started last month for completion in November 2025, mass production from 3Q26
  • Separately, company also plans to build the Yongin Semiconductor Cluster, home to fabs, complex for business partners and infrastructure
  • Four fabs to be ready in order, while suppliers of materials, components and equipment to move in to build semiconductor ecosystem through collaboration with SK hynix
  • Process to form the site underway with progress rate of leveling the ground for 1st fab standing atapproximately 42%
  • Construction of 1st fab to start in March 2025 for completion in May 2027
  • Mini fab to be located within the cluster to help domestic business partners with valuable ideas to develop new technology and win competitiveness by offering opportunities to test under practical circumstances for mass production
  • Cleanroom and human resources to be provided by SK hynix for free, while central and local governments will support investment and operation of equipment
  • SK hynix to work towards strengthening domestic ecosystem and Korea’s leadership in semiconductor industry through Yongin Cluster
