Abstract

Novel nonconductive adhesives/films (NCAs/NCFs) with carbon nanotubes (CNTs) for high-performance interconnects were developed. A small amount of CNTs inside NCAs/NCFs could increase the thermal conductivities and at the same time decrease the coefficient of thermal expansion (CTE) for high thermomechanical reliability of the NCAs/NCFs´ interconnect joints. Thermal mechanical analyzer measurements showed that the CTE value of the 0.03 wt% CNT filled NCAs/NCFs was significantly decreased. Current-voltage characterizations showed that the current carrying capabilities of the CNT (0.03 wt%) filled NCAs/NCFs were increased by 14% compared to the unfilled NCAs/NCFs due to the more efficient thermal dissipation and higher electrical conductivity by CNTs.
