🛠️ Technical Deep Dive
- Glass substrates utilize Through-Glass Vias (TGV) to replace traditional Through-Silicon Vias (TSV) or organic substrate drilling, allowing for higher density interconnects.
- The material exhibits a lower dielectric constant (Dk) and dielectric loss (Df), which minimizes signal attenuation in high-speed data transmission environments.
- Enhanced thermal stability allows for higher power density chips, as glass can withstand higher operating temperatures without significant dimensional deformation.
- The manufacturing process integrates panel-level packaging (PLP) techniques, enabling the production of larger substrate sizes compared to traditional wafer-level processes, thereby improving cost-efficiency for large-die AI accelerators.
