A new technical paper, “Highly energy-efficient manifold microchannel for cooling electronics with a coefficient of performance over 100,000,” was published by researchers at KAIST.
The study presents a CMOS-compatible manifold microchannel cooler that removes over 2,000 W/cm² using single-phase water at only 8 kPa pressure drop, achieving a record COP of 106,000—a significant improvement over prior state-of-the-art liquid-cooling technologies for advanced semiconductor packaging.
The results point to a scalable thermal-management pathway for next-generation heterogeneous integration, 3D packaging, and AI/HPC chips, where thermal density is becoming a primary packaging bottleneck.
