The　miniaturization　of　electronic　devices　into　the　nanometer　scale　is　indispensable　for　next-generation　semiconductor　technology,　and　carbon　nanotubes　are　considered　to　be　the　promising　candidates　for　the　future　interconnection　wires.　To　study　carbon　nanotube　interconnection　during　nanowelding,　we　propose　a　new　nanospot　welding　method　with　the　near-field　enhancement　effect　of　the　metallic　AFM　probe　tip　irradiated　by　an　optical　fiber　probe　laser.　Based　on　theoretically　analyzing　the　near-field　enhancement　effect,　we　set　up　the　experimental　system　for　nanospot　welding　with　good　interconnection　results　of　silver　nanoparticles　and　carbon　nanotubes,　not　only　proving　that　the　interconnection　operation　of　CNTs　can　be　effectively　achieved　through　the　melting　process　of　nanoparticles　by　the　thermal　AFM　probe　tip　irradiated　by　an　optical　fiber　probe　laser,　but　also　providing　a　promising　technical　approach　for　nanospot　welding.
