    摘要： A piezoelectric thin film resonator of the present has a substrate 1, an intermediate layer 7 disposed on the substrate 1 and is formed of an insulator, a lower electrode 3 disposed on the intermediate layer 7, a piezoelectric film 4 disposed on the lower electrode 3, and an upper electrode 5 disposed on a position facing the lower electrode 3 with the piezoelectric film 4 interposed therebetween, in which, in a resonant region 8 where the lower electrode 3 and the upper electrode 5 face each other, a space 6 is formed in the substrate 1 and the intermediate layer 7 or between the lower electrode 3 and the intermediate layer 7 and the region of the space 6 is included in the resonant region 8. With the structure, the dissipation of the vibrational energy to the substrate from the resonance portion can be suppressed, thereby improving the quality factor.

    摘要： A filter has a plurality of piezoelectric thin film resonators formed by sandwiching a piezoelectric film with a lower electrode disposed on a substrate and an upper electrode. Each of the piezoelectric thin film resonators has an electrode region formed with the upper electrode and the lower electrode overlapping each other, whose outline includes a curve. Among the plural piezoelectric thin film resonators, the piezoelectric thin film resonators in the opposing electrode regions of the adjacent piezoelectric thin film resonators are shaped to have outlines complementary to each other. With the filter, influences caused by transverse mode undesired wave of the piezoelectric thin film resonators can be suppressed. Therefore, miniaturization can be achieved without sacrificing the mechanical strength of electrodes having hollow structures.

    摘要： A method of manufacturing an elastic wave device is provided with a lamination step of forming, on a substrate (1), a plurality of elastic wave devices, each of which includes a lower electrode (2), a piezoelectric film (3), and an upper electrode (4); a measuring step for measuring the operation frequency distribution of the elastic wave devices on the substrate (1); and an adjusting step for forming an adjusting region, in which the thickness of the elastic wave device is different from the thicknesses of other portions in a resonance portion of each elastic wave device, corresponding with the distribution of the operation frequencies. The adjusting region is formed so that the size of the area of the adjusting region of the resonator portion of each elastic wave device is different in accordance with the operation frequency distribution that is measured. Thus, the frequency characteristics of the elastic wave devices are easily adjusted by a small number of steps.
