Industry Analysis
The proliferation of sub-3nm nodes is forcing a performance leap in packaging materials, spiking demand for ABF substrates and high-purity epoxy molding compounds while pressuring upstream resin and filler suppliers to accelerate R&D. Geopolitical tensions are driving China’s localization push, yet critical materials like photosensitive polyimide remain heavily reliant on Japanese and U.S. suppliers, heightening supply chain fragility. The 2.5D/3D packaging arms race among TSMC, Samsung, and Intel has triggered preemptive capacity lock-ins by material giants like Sumitomo and Doosan, squeezing out smaller players. Over the next 12–24 months, tightening green regulations—such as EU RoHS upgrades—will raise compliance costs while accelerating commercialization of bio-based alternatives. Despite scale advantages in Taiwan, China and mainland China’s OSAT clusters, persistent gaps in foundational material IP will keep them strategically disadvantaged in the advanced packaging value chain.
