日月光首条CoWoS产线，来了

Core Viewpoint - The article discusses the expansion of TSMC's CoWoS capacity driven by AI demand, highlighting the ongoing supply shortage and the emergence of alternative solutions from competitors like ASE and Siliconware [1][2]. Group 1: TSMC's CoWoS Capacity Expansion - TSMC is significantly expanding its CoWoS capacity, which remains in high demand, with expected monthly production reaching approximately 120,000 to 130,000 units this year, and projected to be around 65,000 to 70,000 units by 2025 [1]. - NVIDIA has secured over half of TSMC's CoWoS capacity for several years, with Broadcom and AMD following as the second and third largest customers, indicating intense competition for available capacity [1]. Group 2: Competitors' Developments - ASE is building its first CoWoS-L packaging line in Kaohsiung, aiming for production by 2027, and is currently validating with customers [1][2]. - Siliconware has a more comprehensive CoWoS production layout, already producing CoWoS-R and starting CoWoS-L capabilities, which helps alleviate customer capacity issues [2]. - Both ASE and Siliconware are positioned to provide alternative advanced packaging solutions, which could optimize product offerings and cost structures for AI chip suppliers facing TSMC's capacity constraints [2].
