Glass Core Substrates Using SCHOTT BF33®: A Widely Spec-In Material Platform for AI and HPC Heterogeneous Integration

4:00 pm - 4:25 pm

The rapid growth of AI accelerators and high‑performance computing (HPC) devices is driving advanced packaging toward larger substrate sizes, higher interconnect density, and tighter warpage and reliability requirements. As a result, the industry is increasingly adopting Glass Core Substrate (GCS) technology to overcome the limitations of conventional organic core materials. Within this transition, SCHOTT BF33®, a borosilicate glass, has become one of the most widely used and commonly spec‑in glass materials for GCS platforms targeting AI and HPC applications.

This presentation will focus on how SCHOTT BF33® enables manufacturable and scalable GCS solutions for AI and HPC packaging through its proven dimensional stability, low and well‑matched coefficient of thermal expansion, excellent surface quality, and compatibility with fine‑line redistribution and through‑glass via (TGV) processing. The discussion will emphasize manufacturing readiness, repeatability, and yield performance, reflecting BF33®’s established position in customer specifications and qualification flows rather than early‑stage development.

Beyond supplying a widely adopted material, SCHOTT supports customers across the AI and HPC packaging ecosystem with application‑focused engineering services, including advanced fractography and failure analysis. By identifying crack initiation mechanisms, handling‑related damage, and process‑induced failures under large‑body and high‑density package conditions, SCHOTT helps substrate manufacturers and OSATs improve yield, reduce risk, and accelerate GCS deployment into high‑volume AI and HPC production.
