iCometrue Unveils Glass-Based AI Multichip Packaging with Embedded Copper Power Blocks

On August 24, 2026, semiconductor packaging architecture pioneer iCometrue revealed its next-generation glass-based multichip packaging platform ahead of SEMICON Taiwan 2026. Designed to overcome the physical thermal warpage and power delivery limits of conventional organic substrates and silicon interposers, the platform embeds solid copper blocks and voltage regulator chips directly into glass panels, reducing required Through-Glass Vias (TGVs) by 80% and establishing a scalable path for multi-kilowatt AI accelerator packaging.

Solving the Through-Glass Via Bottleneck in AI Silicon

While glass substrates offer superior flatness, rigidity, and thermal coefficient matching compared to organic ABF substrates, drilling and plating millions of microscopic Through-Glass Vias (TGVs) has historically created severe yield loss and micro-cracking. iCometrue's architecture bypasses this limitation by embedding solid copper blocks directly into laser-etched cavities in the glass core, providing ultra-low-resistance power and ground delivery without dense arrays of fragile micro-vias.

Key Engineering Innovations

• 80% Reduction in TGV Count: Embedding solid copper blocks replaces dense via clusters, dramatically lowering fabrication complexity and improving panel yield.
• Direct 48V-to-Core Power Delivery: Integrated Voltage Converter/Regulator (VCR) chips stepped down input voltage inside the package, cutting power delivery impedance and I2R heat losses.
• Integrated Silicon Bridges & Decoupling Capacitors: Frontside interconnection layers embed silicon bridge chiplets and deep-trench decoupling capacitors (DTCs) directly over the glass core.
• Scalable HPC Multichip Footprint: Enables massive 70mm+ package sizes connecting logic accelerators and High Bandwidth Memory (HBM) stacks with near-zero substrate warpage.

Advancing Moore's Law Through Glass Heterogeneous Integration

As leading foundries including TSMC, Intel, and Samsung accelerate pilot production of glass substrates for 2026-2028 deployment, iCometrue's embedded copper approach provides a production-ready blueprint for high-yield glass packaging in enterprise AI data centers.
