Abstract We report the experimental results of the prepartion of YBaCuO superconductorthin film on Si (100) substrate by the method of ion beam sputtering deposition. A ZrO_2 buf-fer layer was applied to Si (100) substrate, and was found to play an important role in resist-ing the diffusion of Si toward the film. The thin film is mainly a 123 phase with strong c-axispreferred orentation. The onset transition temperature of the film is 100 K and the finaltransition temperature 78 K.
