Group 1: CoWoS Technology Challenges - CoWoS packaging technology has become a focal point in the industry but is now facing significant challenges such as high production costs, yield control issues, and electrical performance limitations [1][36]. - The increasing size of AI GPU chips and the number of HBM stacks have led to bottlenecks in CoWoS, particularly due to photomask size limitations [4][36]. - TSMC has acknowledged these challenges and is positioning CoPoS as the next-generation successor to CoWoS, aiming to gradually replace CoWoS-L through technological iterations [4][9]. Group 2: CoPoS Technology Development - CoPoS technology represents a significant evolution from CoWoS by replacing the silicon interposer with a panel-sized substrate, allowing for larger packaging sizes and improved area utilization [6][8]. - CoPoS aims to enhance overall computational performance by integrating more semiconductors within a single package, thus improving yield efficiency and reducing edge waste [6][8]. - TSMC plans to establish a pilot line for CoPoS technology by 2026, with mass production targeted for late 2028 to 2029, with NVIDIA as the first customer [9][36]. Group 3: FOPLP Technology Emergence - FOPLP is emerging as a potential major alternative to CoWoS, leveraging the advantages of fan-out wafer-level packaging while utilizing panel-level substrates for enhanced size and utilization [10][13]. - The FOPLP market is projected to grow significantly, with a compound annual growth rate of 32.5%, reaching approximately $221 million by 2028 [14][36]. - Major industry players like ASE, Samsung, and others are actively investing in FOPLP technology, with ASE planning to establish a production line in Kaohsiung and Samsung already having a foothold in the panel-level packaging sector [11][18][19]. Group 4: CoWoP Technology Introduction - NVIDIA has proposed CoWoP technology, which simplifies the traditional packaging structure by integrating the chip directly onto the PCB, potentially reducing costs and improving performance [25][30]. - CoWoP aims to enhance signal integrity and power delivery while reducing thermal issues, but it faces significant technical challenges related to PCB manufacturing capabilities [30][36]. - The transition to CoWoP is seen as a long-term project for NVIDIA, with potential benefits including reduced costs and improved performance, although short-term adoption remains uncertain due to existing dependencies on traditional packaging methods [33][35].
