英伟达采用CoWoP的可能性分析
傅里叶的猫· 2025-08-05 09:52
Core Viewpoint - The recent surge in interest around the semiconductor supply chain is driven by NVIDIA's proposal to use CoWoP (Chip-on-Wafer-on-PCB) technology as a potential replacement for CoWoS packaging technology, leveraging advanced high-density PCB techniques to simplify system structure and improve efficiency [5][9]. Group 1: CoWoP Technology Overview - CoWoP is defined as a method where the chip is directly mounted onto the PCB after the intermediary layer is manufactured, eliminating the need for the ABF substrate used in CoWoS [8]. - The potential advantages of CoWoP include simplified system architecture, reduced transmission losses, improved data transfer efficiency, enhanced thermal management, and lower substrate costs [9][10]. Group 2: Commercial Viability of CoWoP - The likelihood of CoWoP achieving commercial viability in the medium term is considered low due to several technical challenges, including the need for finer line widths and pitches that current PCB technologies cannot meet [11]. - The existing technology roadmap of NVIDIA, which focuses on CoWoS-L and CoPoS, conflicts with the new direction of CoWoP, further complicating its adoption [11][12]. Group 3: Impacts on the Semiconductor Supply Chain - If CoWoP is successfully implemented, it could shift complex signal routing to the re-routing layer, potentially reducing the value of ABF substrate manufacturers while benefiting PCB manufacturers through increased revenue from advanced PCB specifications [15]. - The balance between high-speed performance and the demands for high current/voltage in platform PCBs presents significant challenges, with companies like Unimicron positioned favorably due to their experience in both PCB and substrate technologies [16]. Group 4: Effects on Testing and Manufacturing - CoWoP may reduce the number of final and system-level testing steps, shifting towards board-level testing, although achieving high yield rates is critical for this transition [18]. - The impact on wafer foundries and OSATs is expected to be minimal, as the chip-on-wafer process remains largely unchanged, but the lack of involvement from major players like TSMC raises concerns about the technology's success [19].
