  • Patent number: 10543510
    Abstract: Non-conductive substrates, especially the sidewalls of micro/nano holes thereof are chemically modified (i.e., chemically grafted) by reduced graphene oxide (rGO). The rGO possesses excellent electrical conductivity and therefore the modified substrates become conductive, so that it can be directly electroplated. These rGO-grafted holes can pass thermal shock reliability test after electroplating. The rGO grafting process possesses many advantages, such as a short process time, no complex agent (i.e., no chelator), no toxic agents (i.e., formaldehyde for electroless Cu deposition). It is employed in an aqueous solution instead of an organic solvent, and therefore is environmentally friendly and beneficial for industrial production.
