(English Abstract)
We present a new method for the fabrication of film bulk acoustic wave resonator (FBAR) devices that exploits the thin piezoelectric ZnO films particularly sputter-deposited in a mixture of N2O and Ar gases as the reactive and sputtering gases, respectively. Some thermal annealing treatments were performed on the as-deposited ZnO films and also their effects on the resonance characteristics of the FBAR devices were investigated. It was found that with an optimized process, the resonance characteristics of the fabricated FBAR devices could be further improved.
