半导体芯闻·2025-12-03 10:28Core Insights - The rapid development of artificial intelligence and high-performance computing has led to an increasing demand for heterogeneous integration, making advanced packaging technology a strategic focus [1] - TSMC's CoWoS platform is currently the leading solution in the field, but chip service providers are considering a shift to Intel's EMIB technology due to rising demands for packaging size and complexity [1][2] Group 1: CoWoS Technology - CoWoS technology connects computing logic, memory, and I/O chips through an intermediary layer, with various expansions like CoWoS-S, CoWoS-R, and CoWoS-L [1] - The market is rapidly shifting towards CoWoS-L as NVIDIA's Blackwell platform approaches mass production in 2025, which integrates silicon intermediary layers into the packaging [1] - CoWoS technology faces significant bottlenecks, including capacity shortages and rising manufacturing costs, primarily due to NVIDIA GPU occupying most of the CoWoS capacity [2] Group 2: EMIB Technology - Intel's EMIB offers several advantages over TSMC's CoWoS, such as direct integration of small silicon bridges into the substrate, which simplifies structure and improves production yield [2] - EMIB supports larger effective mask size expansions, with EMIB-M already supporting 6 times expansion, expected to reach 8-12 times by 2026-2027, compared to CoWoS's limits of 3.3 and 3.5 times [3] - EMIB is seen as a more cost-effective solution for AI customers needing ultra-large packaging due to the elimination of intermediary layers [3] Group 3: Market Implications - Intel has invested years in developing EMIB technology since establishing its independent foundry services (IFS) division in 2021, successfully applying it to server CPU platforms [4] - Major North American CSPs like Google and Meta are collaborating with Intel to adopt EMIB, which could significantly drive IFS growth [4] - Despite the potential of EMIB, CoWoS is expected to remain the primary packaging solution for NVIDIA and AMD's high-bandwidth products in the foreseeable future [4]
