半导体行业观察·2025-08-07 01:48Core Viewpoint - The semiconductor industry is experiencing a shift from CoWoS packaging technology to emerging alternatives like CoPoS and FOPLP due to the limitations and challenges faced by CoWoS, including high production costs and capacity bottlenecks [2][39]. Group 1: CoWoS Technology Challenges - CoWoS packaging technology has become a focal point due to the rise of AI and GPU chips, but it faces significant challenges such as complex processes, high production costs, and issues with yield control and testing [2][39]. - The increasing size of AI GPU chips and the number of HBM stacks have led to limitations in CoWoS, particularly due to photomask size constraints [6][39]. Group 2: CoPoS as an Evolution - CoPoS technology is seen as the next evolution of CoWoS, with TSMC positioning it as a successor that offers greater flexibility and economic benefits [4][6]. - CoPoS replaces the silicon interposer with a panel-sized substrate, allowing for larger packaging sizes and improved area utilization, which enhances production flexibility and scalability [8][11]. Group 3: FOPLP Technology Emergence - FOPLP is gaining traction as a potential major alternative to CoWoS, with its ability to support larger chip sizes and higher I/O density, making it suitable for AI and high-performance computing applications [12][14]. - The FOPLP market is projected to grow significantly, with a compound annual growth rate of 32.5%, reaching approximately $221 million by 2028 [18][21]. Group 4: Industry Players and Developments - Major companies like ASE, Samsung, and TSMC are actively investing in FOPLP technology, with ASE planning to establish a production line in Kaohsiung and Samsung having acquired PLP technology to support its development [22][23]. - TSMC is also advancing its FOPLP technology, with plans for a dedicated production line and initial trials expected to begin in 2026 [24][25]. Group 5: CoWoP Technology Introduction - CoWoP, proposed by NVIDIA, aims to simplify the packaging structure by integrating the chip directly onto the PCB, potentially reducing costs and improving performance [29][31]. - However, CoWoP faces significant challenges, including the need for high-precision PCB manufacturing and the risk of yield issues during the transition from existing technologies [35][37]. Group 6: Future Outlook - The semiconductor industry is currently balancing mature technologies like CoWoS with emerging solutions such as CoPoS, FOPLP, and CoWoP, which are expected to reshape the landscape as they mature [39].
