Samsung

Samsung (005930.KS) is a publicly traded Foundries company founded in 1983 and based in Suwon, South Korea.

Samsung operates the world's second-largest semiconductor foundry and manufactures memory, competing with TSMC and SK Hynix. Struggles with advanced-node yields vs TSMC; strong in HBM and DRAM. Gate-all-around (GAA) transistors shipping at 3nm.

Samsung is the only other foundry pursuing leading-edge logic at scale, critical for supply-chain resilience in AI chips.

Bull case

Samsung is the only credible alternative to TSMC for leading-edge logic, and geopolitical pressure for supply-chain resilience is a tailwind that plays directly into its hand. Gate-all-around (GAA) transistors already shipping at 3nm give Samsung a structural technology differentiator — TSMC is still on FinFET at that node. If GAA yields mature, Samsung leapfrogs in power and performance for AI accelerators. Meanwhile, Samsung's dominance in HBM3E memory (stacked DRAM for Nvidia and AMD GPUs) means it captures AI spend from two directions: logic wafers and high-bandwidth memory. The vertical integration play — logic, memory, and advanced packaging under one roof — is something TSMC cannot replicate. Recent Samsung research contributions on memory reliability signal deepening technical moats in the AI stack (source_article_ids:). As hyperscalers demand second sources, Samsung is the only foundry scalable enough to answer. Samsung's foundry business is caught between a dominant incumbent and a capital-intensity trap. TSMC holds roughly 90% of leading-edge market share and consistently delivers better yields at every node — customers simply cannot afford the risk of Samsung's reported sub-50% 3nm GAA yields. The GAA "first-mover" advantage has backfired: Samsung rushed to market while TSMC waited to perfect the transistor, meaning early adopters may flee back to TSMC's 3nm FinFET (which performs competitively) or wait for TSMC's own GAA at 2nm. The foundry division is also chronically under-invested relative to Samsung's memory cash cow — capital allocation favors DRAM/NAND, starving logic of the R&D needed to catch TSMC. Without a marquee external customer like Nvidia or Apple committed to Samsung's advanced nodes, the foundry risks becoming a captive supplier for Samsung's own system LSI division, never achieving the scale needed to compete.
