Samsung Hwaseong V1 Line — 3nm/4nm
Samsung Semiconductor's Hwaseong campus, Line V1 — primary advanced logic production line for 3nm GAA (3GAE/3GAP) and 4nm EUV (4LPP/4LPX) foundry nodes. First in the world to produce 3nm GAA chips (June 2022). Plagued by yield issues: 3nm yields reportedly ~50% after three years (2025), versus TSMC N3 approaching 90%. No major AI chip customer win at 3nm. Samsung has won some orders from Qualcomm (Snapdragon X Elite uses 4nm) and Exynos internal products.
