🛠️ Technical Deep Dive
- Material Composition: Proprietary LTCC (Low-Temperature Co-fired Ceramic) with optimized CTE for silicon integration.
- Via Specifications: 75μm diameter vias with 200μm pitch, utilizing laser-drilling for high-aspect-ratio precision.
- Interlayer Connectivity: Supports high-density vertical interconnects mimicking TSV (Through-Silicon Via) performance without the fragility of silicon interposers.
- Structural Integrity: High Young's modulus significantly reduces substrate deflection during the reflow process in heterogeneous integration.
🔮 Future ImplicationsAI analysis grounded in cited sources
Ceramic substrates will capture significant market share in the AI accelerator segment by 2028.
The increasing size of AI chiplet packages makes traditional organic substrates prone to warpage, forcing a shift toward more rigid materials.
Kyocera will expand this technology to support 3D-stacked memory integration.
The high thermal stability and rigidity of the ceramic core provide an ideal foundation for the high-density vertical stacking required by HBM (High Bandwidth Memory).
