先进封装，全速扩产

Core Viewpoint - The article discusses the significant investment and strategic shifts in the semiconductor packaging industry, particularly focusing on advanced packaging technologies driven by the AI wave and the structural changes in the storage industry [1][2]. Group 1: Investment and Market Trends - SK Hynix announced a 19 trillion KRW (approximately 12.9 billion USD) investment to build an advanced chip packaging factory in Cheongju, South Korea, reflecting the structural changes in the storage industry due to AI [1]. - The global advanced chip packaging market is projected to grow from 50.38 billion USD in 2025 to 79.85 billion USD by 2032, with a compound annual growth rate (CAGR) of 6.8% [2]. - By early 2026, leading packaging and testing companies are expected to ramp up advanced packaging capacity, indicating a competitive landscape focused on advanced packaging capabilities [2]. Group 2: TSMC's Dominance - TSMC is recognized as the leader in advanced packaging, holding over 60% market share in semiconductor manufacturing and establishing significant competitive barriers in advanced packaging technologies [2][3]. - TSMC has developed three branches of CoWoS technology: CoWoS-S for medium-sized chips, CoWoS-R for greater design flexibility, and CoWoS-L for large AI chips [3]. - TSMC's SoIC technology, based on CoWoS and wafer-on-wafer stacking, offers higher interconnect density and improved performance compared to traditional 2.5D packaging [3]. Group 3: Capacity Expansion and Technological Advancements - TSMC's CoWoS capacity is projected to increase 6-8 times from 2023 to 2026, with a CAGR exceeding 60% [5]. - TSMC's new advanced packaging facilities, including the flagship AP6 plant in Zhunan, are designed for full automation and are expected to handle significant orders from major clients like NVIDIA and AMD [5][6]. - TSMC is also expanding its advanced packaging capabilities in the U.S. with plans for two new facilities in Arizona, focusing on SoIC and CoPoS technologies [6]. Group 4: Competitors' Strategies - ASE, as the largest packaging and testing foundry, is benefiting from the advanced packaging trend, with over 60% of its ATM business expected to come from advanced packaging by 2025 [9]. - ASE is developing its own 2.5D packaging platform, FOCoS, and is expanding its production capacity across multiple sites, including a new K28 plant aimed at meeting the demand for AI and GPU chips [10][11]. - Amkor is enhancing its market position through partnerships, such as its collaboration with Intel on EMIB technology, and expanding its facilities in the U.S. to meet advanced packaging demands [15][16]. Group 5: Mainland China's Participation - Mainland Chinese companies are actively investing in advanced packaging technologies and capacity, with firms like Yongxi Electronics and Changjiang Electronics focusing on high-density packaging and automotive electronics [20][22]. - Yongxi Electronics is establishing a new production base in Malaysia to enhance its overseas strategy, while Changjiang Electronics is expanding its automotive electronics packaging capabilities [21][22]. - Tongfu Microelectronics is also increasing its advanced packaging capacity, particularly in automotive and high-performance computing sectors, to meet growing market demands [23][24]. Group 6: Future Outlook - The article concludes that while TSMC's dominance in advanced packaging is unlikely to be challenged in the short term, other specialized packaging firms are seeking to differentiate themselves through flexible capacity and innovative technologies [25][27]. - The collective expansion of packaging firms represents a significant industry bet on the demand for AI-driven computing power, with the potential for winners to emerge as the market stabilizes and technology paths clarify [27].
