TSMC(US:TSM) 傅里叶的猫·2025-07-25 08:24Core Viewpoint - The article discusses the CPO (Co-Packaged Optics) industry chain participants, highlighting the differences between the traditional optical transceiver supply chain and the emerging CPO ecosystem, which integrates silicon semiconductor supply chains and requires upgrades to key components and manufacturing equipment [1][2]. Traditional Optical Transceivers - The traditional optical transceiver supply chain consists of epitaxial wafers, optical components, DSP suppliers, and module manufacturers, dominated by companies like Coherent, Lumentum, and Broadcom [2][3]. CPO Value Chain - The CPO value chain includes various components such as epitaxial wafers, fibers, optical engines, and assembly/testing services, with notable suppliers like TSMC, ASE/SPIL, and Broadcom playing critical roles [4]. Wafer Foundries - Wafer foundries are expected to be foundational for CPO development, with TSMC's COUPE platform likely becoming a key entry point for potential customers seeking CPO solutions [5][8]. - TSMC is collaborating with companies like Broadcom and Nvidia on CPO transceivers, while other foundries like Intel and GlobalFoundries are also targeting the silicon photonics market [8][9]. FAU (Fiber Array Unit) - FAUs are critical components in the CPO supply chain, with TSMC planning to integrate them directly into optical engines [10]. - FOCI is positioned to partner with TSMC due to its high-temperature resistant FAU technology, which is essential for integration into the COUPE platform [10]. Assembly, Packaging, and Testing - Companies like ASE and SPIL are expected to play significant roles in the CPO supply chain due to their expertise in packaging and assembly processes [11]. - Testing is crucial for CPO components, requiring stricter quality control compared to traditional optical transceivers [11]. Equipment Manufacturers - Equipment manufacturers like BESI and ASMPT are poised to benefit from the demand for hybrid bonding equipment driven by CPO developments [14][15]. - GPTC is expected to provide cleaning tools for EIC and PIC stacking, with unique equipment tailored for CPO production [15]. Industry Information Exchange - The article mentions the availability of industry information and analysis reports through platforms like Knowledge Planet, which aims to keep stakeholders updated on market developments [17].
