Summary

SiN (Si₃N₄) AMB substrates refer to silicon-nitride-based active metal brazed copper-clad ceramic substrates used as high-reliability insulating, thermal-management and interconnection platforms in power semiconductor modules. Compared with conventional DBC ceramic substrates, Si₃N₄ AMB substrates are valued for their combination of high mechanical robustness, low thermal resistance, high thermal cycling reliability, electrical insulation and copper-based electrical/thermal conductivity, making them particularly suitable for high-power-density and long-lifetime power modules using SiC MOSFET chips. Their core applications include automotive power electronics, especially EV traction inverters and SiC power modules, as well as renewable energy, traction, industrial drives and other demanding power-conversion systems.
The China SiN AMB substrates market has moved from an import-led niche market into a domestic scale-up cycle. Based on the research data, market revenue expanded from US$48.43 million in 2021 to US$264.54 million in 2025, with particularly rapid growth in 2021–2023 as Chinese EV power module demand accelerated and domestic SiC module packaging capacity expanded. The market is forecast to reach US$953.36 million by 2032, with a 2026–2032 CAGR of 19.20%, indicating that the industry is still in a high-growth stage rather than a mature replacement cycle. By application, automotive is the overwhelming demand anchor, accounting for 90.72% in 2025 and rising to 92.75% by 2032; this reflects the concentration of Si₃N₄ AMB demand in SiC traction inverter modules, high-voltage EV platforms, and high-reliability powertrain packaging. New Energy & Power Grid is the second-largest application, but its share is projected to decline from 5.38% in 2025 to 4.41% in 2032, not because demand is shrinking, but because automotive demand is growing faster. Traction & Railway, Military & Aerospace, Industrial and Others remain technically relevant but relatively small in revenue share. China’s NEV policy environment remains supportive: the State Council’s 2021–2035 NEV plan calls for high-quality NEV development, stronger technology innovation, industry ecosystem building and deeper integration with energy, transportation and information systems; subsequent policy guidance also stresses NEV-grid integration, charging infrastructure and the role of NEVs in the power system by 2030.
The competitive structure is shifting rapidly toward Chinese domestic suppliers, with Jiangsu Fulehua, BYD and Zhejiang TC Ceramic Electronic emerging as the most important domestic players. In 2021, Rogers held the largest China market share at 39.04%, while Jiangsu Fulehua was at 20.13%, Heraeus at 10.29%, Shengda Tech at 5.94%, and BYD at only 3.22%. By 2025, the structure had changed materially: Jiangsu Fulehua ranked first with 33.05%, BYD ranked second with 21.37%, Zhejiang TC Ceramic Electronic rose to 12.62%, while Rogers declined to 12.29% and Heraeus to 5.29%. This shows a clear localization trend driven by domestic EV OEM supply chains, SiC module localization, and the need for shorter lead times and customized module substrate designs. However, the market is not fully commoditized. International vendors still retain technology credibility in high-reliability designs, Ag-free AMB processes, long-term thermal cycling performance and global automotive qualification. At the same time, new Chinese entrants such as Bomin Electronics, Konfoong Materials International, Nantong Winspower, Beijing Moshi Technology, Fujian Huaqing, Guangzhou Xianyi and Hexcera are beginning to appear, but most remain in early scale-up or niche-stage positions. Over the medium term, the competitive gap will depend less on nominal capacity and more on Si₃N₄ bare substrate sourcing, copper/ceramic bonding reliability, AMB patterning yield, silver-cost control, surface finishing capability, customer qualification, and stable mass production for automotive-grade SiC modules. Heraeus’ portfolio highlights the importance of standard and Ag-free Si₃N₄ AMB solutions, while Rogers emphasizes long lifetime, robustness and high-power-density applications, indicating that future competition will be shaped by both cost reduction and reliability differentiation.
The industry chain of China SiN AMB substrates is becoming more localized, but several bottlenecks remain in upstream Si₃N₄ ceramic materials, active brazing materials and automotive-grade process control. Upstream inputs include Si₃N₄ ceramic bare substrates, oxygen-free copper/copper foil, active metal brazing alloys, silver-containing or silver-free brazing systems, plating chemicals, etching chemicals and inspection equipment. Midstream manufacturers perform ceramic metallization, AMB bonding, lithography/etching or mechanical patterning, surface treatment, warpage control, reliability testing and master-card/single-unit delivery. Downstream demand is concentrated in SiC power modules, especially EV main inverters, renewable energy converters, industrial drives and rail traction. The strongest growth drivers are: high-voltage EV architectures, rising SiC penetration, higher module power density, domestic substitution of high-end power module materials, and China’s continued NEV and charging infrastructure policy support. The main constraints are: high-quality Si₃N₄ substrate supply, yield loss during AMB bonding and patterning, thermal cycling qualification cycles, customer validation time, copper and silver price volatility, and the risk of overcapacity among late entrants. The long-term trend is toward thinner ceramic, thicker copper, higher thermal cycling capability, Ag-free or lower-Ag AMB processes, larger master cards, higher automation, and tighter co-design with SiC module makers. Therefore, China’s SiN AMB substrate market should continue expanding rapidly through 2032, but the leading companies will be those that combine stable automotive-grade mass production, upstream material security, cost control and direct qualification with leading domestic and international power module customers.
