A modification of physical properties of solid-state C60 when La was doped to C60 thin film as a trivalent metal was examined. The thin film was fabricated by using Layer-by-Layer deposition technique with the multi-sources evaporation system. We found that the C60 film changes its electrical character from the insulator to the semiconductor rapidly upon La doping. The temperature dependence of the electrical conductivity is semiconductive with the activation energy of about 0.3eV.
