titleOfInvention |
Piezoelectric thin film resonator and manufacturing method thereof |
abstract |
A method of manufacturing a piezoelectric thin film resonator which can reduce variations in resonant frequency and resonant resistance by uniformly planarizing a structural film. The method of manufacturing the piezoelectric thin film resonator includes the steps of forming sacrifice layer patterns on an upper surface of a mother substrate; forming a dielectric film on the sacrifice layer patterns; processing a surface of the dielectric film by a plasma treatment; forming vibration portions on the dielectric film, the vibration portions each being composed of two excitation electrodes and a piezoelectric thin film provided therebetween; etching the sacrifice layer patterns; and cutting the mother substrate into separate piezoelectric thin film resonators. |
