半导体芯闻·2025-11-28 10:46Core Viewpoint - The global semiconductor industry is engaged in a strategic competition centered around the establishment of 2nm wafer fabs, which are seen as critical for AI-era computing sovereignty [1][20]. Group 1: TSMC's Expansion Plans - TSMC plans to increase its 2nm fab count from seven to ten, with an estimated cost of approximately NT$300 billion (US$80-100 billion) per fab, totaling around NT$900 billion for the additional three fabs [2][3]. - TSMC's strategy focuses on serving top-tier clients in AI GPU, high-end CPUs, and mobile SoCs, ensuring long-term capacity even amid macroeconomic fluctuations [2][3]. - The company emphasizes that the most advanced nodes must remain in Taiwan, with overseas fabs primarily serving political and customer relationship needs [3][4]. Group 2: Intel's 18A Technology - Intel's 18A process technology is positioned to compete with TSMC's 2nm, with recent reports indicating a steady improvement in yield rates [6][8]. - The U.S. government has become Intel's largest single shareholder, converting subsidies into equity, which strengthens Intel's capital structure [8][9]. - Intel's success in the 2nm race will depend not only on the 18A technology but also on its ability to establish itself as a true foundry company [9]. Group 3: Samsung's Progress - Samsung's 2nm process yield has improved to 55-60%, with plans to increase monthly production from 8,000 wafers in 2024 to 21,000 by the end of 2025 [10][12]. - The company secured a significant contract with Tesla for AI6 chip production, valued at US$16.5 billion over eight years, which is crucial for enhancing Samsung's position in the U.S. foundry market [11][12]. - Samsung aims to regain profitability in its foundry business within two years while targeting a 20% market share [12][13]. Group 4: Japan's Rapidus Initiative - Rapidus, a smaller player, is focused on establishing domestic 2nm production capacity with government support, aiming for mass production by the second half of the 2027 fiscal year [15][17]. - The company plans to build a second factory in Hokkaido, with significant investment expected from the Japanese government and private sector [17][18]. - Rapidus's approach involves a unique single-wafer processing method, which may lead to higher capital expenditures but aims for better yield control [18]. Group 5: Market Dynamics and Geopolitical Implications - The 2nm node is viewed as a critical infrastructure for AI, with significant implications for capital expenditure and industry dynamics [20][21]. - The construction of 2nm fabs is heavily influenced by government policies and partnerships with major clients, making it a tool for national industrial policy [21][22]. - The concentration of 2nm production capacity in Taiwan and a few allied nations raises concerns about supply chain resilience and geopolitical risks [22]. Group 6: Potential Beneficiaries - Semiconductor equipment manufacturers are expected to benefit significantly from the construction of 2nm fabs, as these facilities require advanced equipment for production [24]. - Major clients like NVIDIA, Apple, and AMD will gain more bargaining power with multiple 2nm suppliers, but risks remain if AI demand declines or yields do not meet expectations [25][26].
