Zheng Quan Shi Bao Wang·2025-11-25 12:35Core Insights - The demand for AI HPC (High-Performance Computing) is driving the need for advanced packaging solutions, particularly TSMC's CoWoS technology, but some cloud service providers (CSPs) are considering Intel's EMIB technology due to increasing chip integration requirements [1][2] Group 1: CoWoS Technology - TSMC's CoWoS solution connects different functional chips using an interposer, with various versions like CoWoS-S, CoWoS-R, and CoWoS-L developed [1] - The market demand is shifting towards CoWoS-L, especially with NVIDIA's upcoming Blackwell platform set for mass production in 2025 [1] Group 2: EMIB Technology - EMIB offers several advantages over CoWoS, including a simplified structure that eliminates the expensive interposer, leading to higher yield rates [2] - EMIB has a smaller thermal expansion coefficient issue due to its design, which reduces the risk of packaging warping and reliability challenges [2] - EMIB can achieve larger packaging sizes, with EMIB-M already supporting 6 times the mask size, and projections for 8 to 12 times by 2027 [3] Group 3: Market Dynamics - The demand for CoWoS is facing challenges such as capacity shortages and high costs, prompting CSPs like Google and Meta to explore EMIB solutions [2] - Intel's EMIB technology has been in development since 2021 and is already applied in its server CPU platforms, with Google planning to implement it in TPUv9 by 2027 [3] - NVIDIA and AMD, which require high bandwidth and low latency, are expected to continue using CoWoS as their primary packaging solution [3]
