摘要：

Cooling presents a significant challenge for high-performance three-dimensional integrated circuits (3D ICs). To this end, this research explores through-silicon via (TSV)-compatible micropin-fin heat sink (MPFHS) for high-power 3D chip stacks. Copper TSVs with a diameter of 5.2 mu m and a high aspect ratio of 29:1 are developed. An extensive experimental and computational investigation of the MPFHS under varying flow rates and power conditions was conducted, showing that the MPFHS maintains an average chip temperature below 72 degrees C, even with a total power dissipation of 500 W and a power density of 312 W/cm (2) at a flow rate of 117 mL/min. The minimum total thermal resistance achieved was 0.286 degrees C<middle dot>cm (2) /W.
