| Research Abstract |
The ultrasonic microspectroscopy technology was applied to evaluation of glass thin films. Two SiO2/Ta2O5 multilayer films were deposited on SiO2 glass substrates by rf ion beam sputtering, and one of them was annealed. Frequency characteristics of leaky surface acoustic wave (LSAW) velocity were measured for specimens by the line-focus-beam ultrasonic material characterization system, and LSAW velocity changes due to the annealing were detected. TiO2-SiO2 thin films were also deposited on SiO2 glass substrates or TiO2-SiO2 glass substrates, and LSAW velocity changes due to the fictivetemperature changes of films were detected.
