Patent ID: 6989325

Claim:
A self-assembly method for fabricating nanometer conductive bumps comprising the steps of: providing a multiplicity of carbon nanotubes, each of said multiplicity of carbon nanotubes having two free ends; attaching to said two free ends of said multiplicity of carbon nanotubes a plurality of functional groups; providing a template having at least one metal pad on a surface; attaching said multiplicity of carbon nanotubes to said at least one metal pad by an attraction force existed between said plurality of functional groups on said free end of said carbon nanotubes and said metal pad; attaching a multiplicity of nanometer metal balls to the other free end of said multiplicity of carbon nanotubes forming a nanometer metal layer; providing a substrate having at least a bond pad on a surface; attaching said nanometer metal layer on said multiplicity of carbon nanotubes to said bond pad on the substrate; and removing said template.
