Advanced Logic Chips (CPU/SoC ≤5nm)

Taiwan Semiconductor Manufacturing Company (TWSE: 2330; founded 1987 by Morris Chang); the world's dominant pure-play foundry and the most critical single company in the global technology supply chain. TSMC manufactures approximately 90% of all sub-5nm logic chips globally, including every NVIDIA AI GPU (H100 on N4, H200 on N4X, B200 on N3E), every Apple processor (A18 on N3E, M4 on N3E), and every AMD data center chip. TSMC's N3 and N5 fabs are located in Taiwan — 100 miles from mainland China. Revenue: $93.7B (2024, +34% YoY). AI/HPC share of revenue: 57% (Q3 2025), up from 18% in 2019. N2 volume production began Q4 2025 at Fab 22 Kaohsiung — world's first 2nm logic node in production. TSMC Arizona Fab 21 Phase 1 (N4P) reached 92% yield and profitability in 2025. CHIPS Act recipient: $6.6B grant + $5B loan.

Samsung Foundry is the semiconductor contract manufacturing division of Samsung Electronics (KRX: 005930); the only sub-5nm foundry competitor to TSMC. Samsung was first to production with GAA (gate-all-around) transistors at 3nm (3GAE, June 2022) but has been plagued by yield problems: 3nm yields reportedly stuck at ~50% after three years of production (2025) versus TSMC's ~90% on N3. No major AI chip customer win at 3nm — Qualcomm abandoned dual-foundry Samsung strategy in favor of exclusive TSMC. Samsung holds ~7-10% of sub-5nm advanced logic market. Hwaseong and Pyeongtaek Korea fabs are primary advanced logic sites. Taylor, Texas fab (4nm, $25B investment) under construction. CHIPS Act recipient: $6.4B grant. Samsung's strongest foundry position is HBM memory (Pyeongtaek P3/P4) rather than logic.

Intel Corporation's external foundry business (Nasdaq: INTC; spun into Intel Foundry Services in 2021 under Pat Gelsinger; accelerated under CEO Lip-Bu Tan from 2024). Intel is attempting to become the third advanced logic foundry at sub-7nm, targeting 18A (1.8nm-class) and 20A process nodes. 18A uses RibbonFET (Intel's GAA transistor) and PowerVia (backside power delivery) — the most aggressive process technology on the roadmap. However, 18A yields were reportedly ~10% at risk production (August 2025), far below the 70-80% needed for external customer viability. Intel 4 (Leixlip Ireland, Fab 34) is in volume production for internal products. Ohio New Albany fabs (Intel 18A, $20B investment) under construction. CHIPS Act recipient: $8.5B grant. Intel Foundry holds ~1-2% of advanced logic market — primarily Intel's own Panther Lake CPUs and Lunar Lake. External customer viability expected 2027 at earliest.

Semiconductor Manufacturing International Corporation (HKEX: 0981; SSE: 688981; founded 2000; headquartered Shanghai) is China's largest and most advanced semiconductor foundry. SMIC is effectively blocked from acquiring EUV lithography equipment by Dutch export controls (enforced since 2019 at US pressure), limiting SMIC's advanced node capabilities. SMIC achieved a '7nm-equivalent' process (N+2) using DUV (deep ultraviolet) multi-patterning — found in Huawei Mate 60 Pro's Kirin 9000s chip (September 2023, shocking Western intelligence analysts). However, SMIC's DUV-based 7nm has significantly lower yields and higher cost than TSMC/Samsung EUV 7nm, limiting competitiveness. SMIC cannot access 5nm or below without EUV. Revenue: $8.03B (2023). SMIC is on the US Entity List (December 2020) — restricting US equipment and software exports.

NVIDIA Corporation (Nasdaq: NVDA; founded 1993 by Jensen Huang, Chris Malachowsky, Curtis Priem) is a fabless semiconductor company and the dominant supplier of AI accelerators. NVIDIA designs all chips in-house but outsources 100% of fabrication to TSMC Taiwan. H100 (Hopper) on TSMC N4; H200 on N4X; B100/B200/GB200 (Blackwell) on N3E. NVIDIA surpassed Apple as TSMC's largest customer in 2025 ($23.4B, 19% of TSMC revenue, +62% YoY). Revenue: $130B (FY2026 guidance). AI data center segment: ~88% of total revenue. NVIDIA's GPU monopoly in AI training (95%+ share of AI accelerator market) means that global AI infrastructure buildout is physically dependent on TSMC Taiwan fabs. A Taiwan Strait crisis that halted TSMC production would immediately freeze global AI infrastructure expansion.
