Samsung Foundry Utilization Rebounds Above 80%
Samsung Foundry's utilization rates climbed above 80% in the first quarter of 2026, signaling a rebound for its advanced node business. The recovery is reportedly driven by the ramp-up of HBM4 memory and Exynos chip production. This resurgence intensifies competition with TSMC for 2nm process technology, potentially impacting foundry pricing and timelines for major customers.
- Samsung's 2nm process (SF2), a key driver of the utilization rebound, is based on Gate-All-Around (GAA) transistor architecture. This technology surrounds the channel on all four sides, which improves power efficiency and performance by enabling finer control of the electric current and minimizing leakage. Samsung's version of this technology is called Multi-Bridge Channel FET (MBCFET). - The Exynos 2600, expected to be featured in the Galaxy S26 series, will be one of the first chips manufactured on this 2nm process. It features a 10-core CPU design and is projected to be 25-30% more power-efficient than its 3nm predecessor, the Exynos 2500. - While Samsung's market share in the foundry sector was approximately 7-10% in late 2025, significantly trailing TSMC's ~70% share, the company is aggressively pursuing new orders. Samsung has reportedly secured a major $16.5 billion deal with Tesla for its next-generation AI chips and is in discussions with other major U.S. and Chinese tech companies. - The company has faced significant challenges with production yields on its advanced nodes; its first-generation 3nm process reportedly achieved yields of 50-60%, while the second-generation was at a much lower 20% as of late 2024. However, the 2nm process yield has reportedly reached around 60%, a level considered sufficient for mass production. - HBM4 memory is set to feature a wider 2048-bit interface, double that of HBM3, enabling significantly higher bandwidth. Mass production from key suppliers like Samsung and SK Hynix is anticipated to begin in earnest in 2026 to align with the release of next-generation AI accelerators from companies like Nvidia. - To bolster its competitive position, Samsung is making substantial investments in advanced packaging, a critical area for high-performance computing. This includes a planned R&D center in Yokohama, Japan, and a potential $7 billion packaging facility in the U.S. as part of a larger investment in its Taylor, Texas site. - TSMC, Samsung's primary competitor, is also on track for 2nm mass production in the latter half of 2025, with major customers like Apple, NVIDIA, AMD, and MediaTek already lined up. Apple is expected to be the first to adopt TSMC's 2nm chips for its future iPhone and Mac processors. - Samsung is targeting a significant increase in 2nm orders for 2026 and is developing its 1.4nm process, which is planned for mass production in 2029. This forward-looking roadmap is crucial for competing with TSMC, which is also planning for 1.4nm production by 2027.
