Bi(-Pb)-Sr-Ca-Cu-O thin films were prepared on MgO(100) single-crystal substrates by electron cyclotron resonance (ECR) plasma sputtering at substrate temperatures from room temperature to 590 /degree/C. Pb-doped superconducting as-grown films were obtained above 560 /degree/C. The /ital T//sub /ital c// values of the Pb-doped films prepared at 570--590 /degree/C were 58--64 K which increased with increasing substrate temperature. Pb-undoped as-grown films obtained at 590 /degree/C showed superconduction (/ital T//sub /ital c// =30 K), but the films obtained below 580 /degree/C were semiconductors. The grain sizes and contents of the 37 A phase (110 K phase) were increased by the Pb doping into the as-grown Bi-Sr-Ca-Cu-O films.
