SK Hynix Korea Fabs (M10-M16 + M15X)

SK Hynix is the world's largest HBM (High-Bandwidth Memory) supplier, holding approximately 53% of the HBM market as of Q3 2025. Its Korea network of fabs produces DRAM, HBM3E, and HBM4 for AI accelerators including NVIDIA's Blackwell and Rubin platforms.

M15X (Cheongju) - SK Hynix's first new fab since its 10th anniversary. Construction began in October 2022 and finished two months ahead of schedule. Originally planned to begin wafer insertion in June 2026, the company started commercial production of 1b DRAM (HBM4 core die) in February 2026 (four months early) to meet NVIDIA demand. Initial capacity ~10,000 WPM, ramping to 55,000-60,000 WPM by Q4 2026. The fab was launched in May 2026, as reported.

Total DRAM capacity (with M15X) is ~550,000-600,000 WPM, ramping toward parity with Samsung's 650,000 WPM by H2 2026. Yongin Semiconductor Cluster is an upcoming four-fab National Industrial Complex with an estimated investment of ~600 trillion won (~USD 430 billion). Phase 1 fab targets completion in May 2027. When fully ramped, it will add ~350,000 WPM, lifting total capacity to ~900,000 WPM.

TSMC Taiwan Network (all fabs)

TSMC is the world's largest pure-play foundry with 65% of the global foundry market share and approximately 92% of the sub-5nm market by revenue. Its annual capacity exceeded 17 million 12-inch equivalent wafers in 2025, the company's biggest year ever. The network includes six 12-inch GigaFab® facilities, four 8-inch fabs, and one 6-inch fab.

Key Taiwan fabs include Fab 12 (Hsinchu, 0.15μm-0.10μm), Fab 14 (Hsinchu, 20nm-5nm), Fab 15 (Taichung, 28nm-40nm, ~100,000 WPM), Fab 18 (Tainan, 3nm-5nm, see separate entry), and Fab 20 (Tainan, 2nm).

2nm ramp: TSMC entered 2nm (N2) mass production in late 2025. Monthly capacity is expected to reach nearly 100,000 WPM by the end of 2026, with Apple as the launch customer and NVIDIA's next-gen "Rubin" platform expected in 2026. 3nm capacity is simultaneously expanding toward 180,000-200,000 WPM by end-2026.

At its Q1 2026 earnings call, Chairman C.C. Wei reaffirmed Taiwan as the primary base for leading-edge production. TSMC's total advanced capacity remains booked through 2028, with 2nm wafer pricing expected to exceed USD 30,000/wafer. TSMC is planning annual price hikes of 3-5% for sub-5nm nodes through at least 2029. Fab 18B's P7 and P8 phases are currently being equipped, with all eight phases expected to deliver ~200,000 WPM of 3nm capacity.

TSMC Fab 18 (Tainan gigafab)

TSMC's fourth and largest 12-inch GigaFab® in Taiwan, and the single largest advanced-logic fab in the world. Built on 42 hectares with a floor area of 950,000 m² and a cleanroom area of 160,000 m² (equivalent to 25 football fields). Fab 18 is purpose-built for TSMC's most advanced nodes and powers chips for Apple, NVIDIA, AMD, and Qualcomm.

SMIC Shanghai (Zhangjiang + Lingang)

SMIC is China's largest and most advanced semiconductor foundry and the anchor of China's strategy for domestic semiconductor self-sufficiency. It is the fourth-largest foundry globally by revenue. The Shanghai campus includes multiple fab lines operating nodes from 0.35μm down to 7nm (achieved via multi-patterning DUV, as EUV is inaccessible under US export controls).

SMIC's 7nm DUV multi-patterning capability - confirmed in chips found inside Huawei's Mate 60 Pro (2023) - represented a major milestone, demonstrating that China could achieve near-leading-edge production without ASML's EUV machines. 

SMIC cannot currently reach 5nm or below, limiting competitiveness against TSMC and Samsung for AI chip orders. Its strength lies in mature nodes (28nm, 40nm, 65nm), which are critical for automotive, IoT, consumer electronics, and industrial chips.

SMIC's Shanghai (USD 8.87 billion) and Tianjin (USD 7.5 billion) fabs targeting 28nm are nearing completion, with operations expected to start in 2025-2026. Huawei and SMIC are reportedly aiming for the 5nm node using aggressive multi-patterning DUV techniques, though yield challenges remain. YMTC (memory peer) announced a third memory fab in China.

TSMC Fab 15 (Taichung)

TSMC's 28nm-40nm workhorse fab and one of its largest mature-node production facilities. Built on 18.4 hectares with a building area of 430,000 m² and a cleanroom area equal to 14 football pitches. Fab 15A produces 28nm and 40nm chips at ~100,000 12-inch WPM, and Fab 15B was converted to supplement 3nm production and has been ramped to full load.

Fab 15B is now operating at full load with a stable 4,500-5,000 wafer daily output at 3nm, supplementing Fab 18B's 3nm capacity. The mature-node segment at Fab 15 continues to serve automotive and IoT customers, where demand for 28nm nodes remains strong and growing.

Intel Ocotillo (Fab 42 + Fab 52)

Intel's primary advanced manufacturing site in the US is the most advanced logic fab in the Americas. The Ocotillo campus, one of the largest semiconductor fabs in the US, spans approximately one square mile (700 acres) and now houses three high-volume fabs (Fab 42; Fab 52, and Fab 62 in construction). Intel began manufacturing in Arizona in 1979 and has since invested over USD 50 billion at the site.

Fab 52 (18A / 1.8nm-class): Construction started late 2021 and is fully operational as of late 2025. Uses GAA (Gate-All-Around) RibbonFET transistors and PowerVia backside power delivery. Production capacity at full ramp is ~40,000 WSPM (10,000 wafer starts/week). 

Equipped with at least 4 ASML NXE Low-NA EUV scanners, with a total planned 15+ EUV machines across the Ocotillo campus. Handles roughly twice the wafer volume of TSMC's Fab 21 Phase 1 at a more advanced node. Fab 62 (14A) - construction began in 2024 and expected completion ~2027-2028. It will use next-generation Intel processes for AI and HPC chips.

GlobalFoundries Dresden (Fab 1)

Europe's largest semiconductor fab and the continent's most important foundry facility. Originally built by AMD as part of a joint venture with Fujitsu, it was spun out into GlobalFoundries in 2009. The Dresden Fab 1 specializes in 22nm FD-SOI (22FDX) and 12nm FDX process technologies, mature but highly efficient nodes suited to RF chips, automotive, IoT, and low-power applications.

The fab employs thousands of workers and is a cornerstone of Germany's semiconductor ecosystem. Its 22FDX process is uniquely competitive for automotive radar, RF front-ends, and microcontrollers. 

The German government confirmed EUR 495M in Chips Act support for GF's EUR 1.1B Dresden expansion plan. GF also announced in June 2025 a broader USD 16B US investment across its New York and Vermont fabs. A planned joint fab in Crolles, France, with STMicro has stalled.

TSMC Fab 21 (Phoenix, Phase 1)

TSMC's flagship US fab is the only sub-5nm manufacturing facility on American soil. Phase 1 (Fab 21 P1) produces 4nm/5nm chips and came online in late 2024, initially at 10,000 WPM and ramping toward 30,000 WPM. Apple is the largest customer, receiving "tens of millions" of Apple Silicon chips in 2025 and over 100 million chips planned for 2026. NVIDIA is also using Fab 21 for some Blackwell AI accelerator production.

The facility employs ~3,000 engineers and uses approximately 700 FOUPs (Front-Opening Unified Pods) on automated overhead transport systems, with EUV lithography as its cornerstone. An industrial water reclamation system recycles up to 90% of the water used.

Phase 2 (3nm): Construction completed April 2026. Equipment installation to begin Q3 2026 (accelerated from original 2028 target), with volume production targeted for 2027. This is years ahead of the original plans.

Phase 3 (2nm/A16): Broke ground in April 2025 and production targeted by the end of the decade.

TSMC Kumamoto JASM (Phase 1)

Japan's most advanced semiconductor fab and TSMC's first overseas GigaFab. Phase 1 (JASM Fab 1) produces 22nm/28nm chips with a focus on automotive, IoT, and industrial applications, nodes in high demand among Japanese OEMs like Toyota and Sony. It opened on schedule in February 2024, marking a milestone in Japan's semiconductor revival strategy.

Phase 2 (JASM Fab 2, 6nm/7nm): The plant is under construction with expected production ~2027. The Japanese government is providing additional subsidies. Recent reports indicate TSMC is upgrading Phase 2 targets from 6nm to 3nm to serve automotive and AI customers, a significant elevation from original plans.
