The author argues that managing heat dissipation in semiconductor transistors is crucial due to localized hotspots, proposing the use of ultrathin silicon carbide to reduce thermal boundary resistance significantly.

Computer components are getting smaller and more powerful, making heat dissipation critical for semiconductor transistor design. Localized hotspots form due to confined electric fields, with synthetic diamond considered the best cooling strategy. However, resistance to heat flow can occur at the interface between diamond and common semiconductor materials like silicon and gallium nitride. Woo et al. have introduced a method using ultrathin silicon carbide to lower thermal boundary resistance significantly, as discussed at the International Electron Devices Meeting.
Statisztikák
The peak temperature of today’s transistors is mainly determined by localized hotspots.
Synthetic diamond is an efficient strategy for cooling hotspots but can lead to resistance at the interface with common semiconductor materials.
Ultrathin silicon carbide proposed by Woo et al. reduces thermal boundary resistance to record low values.
