Asahi Kasei enters advanced semiconductor packaging market with glass fiber cloth for AI chips
Wednesday, April 1, 2026 at 02:57 AM
Asahi Kasei is entering the market for specialized glass fiber cloth used in advanced semiconductor packaging to meet the demand from the AI chip sector. The company's new material aims to provide high stability and reduced signal loss for high-performance computing applications as traditional organic substrates reach their physical limits.
Context
Japanese materials giant Asahi Kasei has announced its entry into the advanced semiconductor packaging market with the production of specialized glass fiber cloth. This material is a critical component for the IC substrates used in high-performance AI chips, such as Nvidia's GPUs. By April 2026, the global supply chain for T-glass—a low-thermal-expansion variant—has become a major structural bottleneck. Current market leader Nittobo and a handful of Japanese firms control over 70% of the global market, making Asahi Kasei's entry vital for supply chain diversification. The company aims to triple its electronics materials sales by 2030 to capture this soaring demand.
This expansion is driven by the shift toward advanced packaging technologies like CoWoS and SoIC, which require high-dimensional stability to prevent warping under intense heat. As major hyperscalers including Apple, Google, and Amazon scramble to secure packaging materials, the supply of high-grade glass cloth is expected to remain strained until at least 2027. Asahi Kasei's strategic move, backed by a 16 billion yen investment in related insulating materials, positions it to alleviate these shortages while supporting the next generation of AI data center infrastructure.
