New Cu/diamond composites push thermal limits in advanced chip packaging

By PulseAugur Editorial · [1 sources] ·

Copper is reaching its performance limits for advanced semiconductor packaging, prompting the development of new materials. Cu/diamond composites are emerging with double the thermal conductivity of pure copper, offering improved heat dissipation and reduced warpage. The primary challenge lies in creating a strong, thin interface between copper and diamond, with ongoing research focusing on carbide bonding layers and pre-coating diamond particles. AI

IMPACT Improved thermal management in advanced packaging could enable more powerful and efficient AI hardware.

    Copper is starting to hit its limits in advanced packaging.

    Copper is starting to hit its limits in advanced packaging. Pure Cu is ~400 W/m·K, while at Semicon Taiwan there are debut of Cu/diamond composites reaching ~800 W/m·K, helping spread heat faster and reduce local hotspots. They can also reduce warpage: silicon is ~3 ppm/K CTE vs …
