NOVELTY - The utility model relates to the technical field of electronic component radiating field, especially a silicon-based bonding graphene radiating copper-clad ceramic substrate, comprising a copper foil layer orderly set from top to bottom, a ceramic layer and a silicon-based bonding graphene coating, the silicon-based bonding graphene coating is set on the lower surface of the ceramic layer, the copper foil layer is covered on the upper surface of the ceramic layer. The utility model uses chemical vapour deposition (CVD) process, taking silicon-containing compound as silicon source catalyst, hydrocarbon as carbon source precursor, growing and depositing a silicon-based bonding graphene coating on the surface of the copper-coated ceramic layer, The heat generated by the circuit or the electronic device etched on the copper foil layer can be quickly radiated out through the ceramic substrate and the silicon-based graphene coating layer.
