Advanced packaging substrates hit limits; ceramic cores rise to challenge glass materials

The technological constraints of conventional glass-based substrates are accelerating the industry's shift toward ceramic core materials, fundamentally reshaping the entire semiconductor manufacturing ecosystem. As AI chip demands intensify, traditional FR4 substrates are failing to meet requirements for thermal expansion, signal integrity, and high-density interconnects, compelling upstream material suppliers to rapidly advance ceramic solutions. This transition will redefine midstream packaging processes, forcing equipment and process node upgrades. From a compliance perspective, the global supply chain realignment enhances the strategic importance of ceramic material self-sufficiency, though short-term production costs will rise. Competitors may pursue M&A or technology control strategies to secure market dominance. Over the next 12–24 months, ceramic core adoption will surge, particularly in high-end AI packaging, establishing new technical barriers and market dynamics.
