New Nano-Thermal Interface Materials (Nano-TIMs) with SiC Nano-Particles Used for Heat Removal in Electronics Packaging Applications

Abstract

Heat dissipation of semiconductor packages has become one of the limiting factors in miniaturization. A new Nano Thermal Interface Material (Nano-TIM) with potential high thermal conductivity and excellent mechanical properties manufactured by electrospinning process has been published earlier. In the present work, SiC nano-particles were added into the electrospinning solution to improve the thermal conductivity of the film. The produced Nano-TIM has a nano scale structure with embedded nano-SiC distributed randomly. Scanning Electrical Microscope (SEM) was used to determine the morphology of the film. Thermal properties were measured. The results show that the Nano-TIM has good thermal properties and it can be further improved by changing the mass concentration of the SiC nano particles.
