The Glass Core Substrate Market and Development Trends (GCS) report, developed by SEMI and Global Net Corp (GNC), examines glass core substrates as an emerging technology for AI, HPC, and advanced semiconductor applications. It covers manufacturing challenges, supply chain structure, company activity, and market outlook through 2040.
As package sizes and performance demands grow, glass core substrates offer critical advantages over organic cores: thermal stability, flatness, rigidity, electrical performance, and CTE alignment with silicon. Understanding where they fit helps inform technology selection, supplier engagement, R&D prioritization, and strategic planning.
❙ What’s at Stake
Glass core substrates’ limited-volume production is expected around 2028 in selected applications, with a projected 67.2% CAGR from 2028 to 2040. However, the market remains in an exploratory stage, with qualification progress, supply-chain readiness, and industry standards still evolving. With many manufacturing bottlenecks still unsolved, this report provides a baseline for organizations that need to track these developments before committing to production timelines.

This report is based on publicly available company information, financial statements, industry materials, and expert interviews. Company sales figures and other data are generally drawn from public sources, while selected market views and trend assessments include estimates based on expert interviews.
The report reflects information available at the time of research. Because the glass core substrate market remains in an exploratory stage, and views differ by region, process segment, and company position, market forecasts and mass-production timing should be interpreted as estimates rather than fixed outcomes. Actual adoption may vary depending on qualification progress, supply-chain readiness, and the emergence of clearer industry standards.
