Amorphous films were annealed for 2 hours at 865℃ to produce the high-T_c phase in a Pb-free Bi-Sr-Ca-Cu-O system, and the quality of the superconducting film was evaluated with X-ray diffraction. The amount of the high-T_c phase was large in the films deposited without heating as compared with the film deposited on a substrate heated at 300℃. The amount in the film deposited at 300℃ increased by irradiation with 200 keV neon-ion to 1×10^<13> cm^<-2> before the annealing. The high-T_c phase could not be observed in the sample containing a low-T_c phase before the final annealing. The results indicated that the high-T_c phase formed directly from substantially amorphous films.
