High quality ZnO thin films were deposited onto InP substrates by radio frequency magnetron sputtering. It was found that the characteristics of ZnO film depend on deposition parameters, and a detailed study was performed. By adjusting these parameters, we obtained a ZnO thin film with an extremely sharp x-ray diffraction peak with a 0.183° full width at half-maximum. The resistivity of the deposited ZnO film is 1010 Ω cm and its refractive index is close to that of single crystal ZnO. These results indicate that the quality of these ZnO thin films is acceptable for the fabrication of a surface acoustic wave device on InP substrates.
