|CerapheneTM – a stack of CVD graphene and ceramic materials (2D) for thermal management of 2.5D/3D packages|
|Keywords: Thermal Interface materials, Graphene thermal management , Ceramic thermal management|
|Two-dimensional (2D) graphene and ceramic materials (CerapheneTM), with outstanding optical, electronic, and mechanical properties has been designed as a building block to realize 3D materials for thermal interface materials (TIM). By the stacking of graphene and ceramic layers, a 3D macroscopic architecture with tunable hierarchical morphologies and high surface areas could be realized. In this way the nanoscale phenomena could be translated to the macroscopic level, paving the way to realizing novel applications such as thermal management of 2.5D and 3D packages including high temperature applications. In this talk, we will describe Cactus proprietary design and developed Graphene and ceramic films grown on nickel films and foils using thermal chemical vapor deposition (CVD) and Atomic Layer Deposition (ALD). Using acetylene-helium and hydrogen-argon gases as precursor gases, high quality growth of graphene was obtained on nickel foils. We observed that quality of graphene and nanotube/graphene ratio improved with higher growth temperature. Optical microscopy, micro-Raman spectroscopy, and transmission electron microscopy investigation revealed that using this technique a high quality and large area graphene can be obtained. We then alternatively added 2D ceramic materials as matrix to conform substrate and simultaneously, adding polymer can provide flexibility as a support structure.|
