Core Viewpoint - The article highlights the significant advancements in semiconductor advanced packaging technology, particularly the introduction of domestic D2W hybrid bonding equipment, marking a breakthrough for Chinese companies in the high-end packaging sector [1][4]. Market Overview - The hybrid bonding technology transitions from solder bump to copper-copper direct bonding, achieving nano-level precision interconnection and addressing the bottlenecks of traditional micro-bump technology in high-density packaging. The global hybrid bonding equipment market was valued at $320 million in 2020 and is projected to reach $230 million for CoW (Chip-on-Wafer) and $510 million for WoW (Wafer-on-Wafer) by 2027, with CAGRs of 69% and 16% respectively, indicating strong growth potential in this field [2]. Supplier Landscape - The hybrid bonding equipment market has been dominated by international giants such as EVG and Besi. The latest Yole report includes the D2W hybrid bonding equipment from ACCURACY, the first Chinese D2W supplier to be featured, and also includes Piotech's W2W equipment set to be released in 2024. This reflects a technological breakthrough for China's semiconductor equipment industry, showcasing its capability to compete with international manufacturers [4]. Application Growth - The demand for high-density packaging is increasing due to the explosion of AI computing power, leading to a rising penetration of hybrid bonding in high-end packaging scenarios such as HBM (High Bandwidth Memory) and 3D ICs. For instance, the penetration rate of hybrid bonding in the HBM market is expected to surge from 1% in 2025 to 36% by 2028 [6]. International Players' Strategies - Major international players are actively positioning themselves in the hybrid bonding space: - Samsung signed a hybrid bonding patent licensing agreement with Yangtze Memory Technologies in February 2025, planning to mass-produce the next generation V10 NAND flash using W2W hybrid bonding technology [8]. - Micron established a dedicated HBM business unit in April 2025 to accelerate its HBM4 mass production plans, with expectations to launch HBM4 products using hybrid bonding technology in 2026 [8]. - SK Hynix plans to incorporate hybrid bonding technology into its HBM4 production process by 2026 [8]. - TSMC and Intel are also advancing their hybrid bonding capabilities, with TSMC supporting HBM4 integration and Intel achieving breakthroughs in CoW technology [8]. Industry Implications - The technological breakthroughs by Chinese packaging equipment companies provide diversified equipment options for the global semiconductor packaging industry, promoting a more open competitive landscape in high-density interconnection technology [9].
