摘要： A method for manufacturing a piezo-resonator including: a first step of forming an upper electrode layer 20 on the piezoelectric film 14, a second step of coating the upper electrode layer 20 with a resist 21 and of performing patterning on the resist so as to have a shape of the upper electrode, a third step of masking the patterned resist 21 and removing the upper electrode layer 20 other than masked portions and forming two or more first upper electrodes 15a, a fourth step of removing the resist 21, a fifth step of coating the first upper electrodes 15a with a resist and performing patterning on the resist so that the first upper electrodes 15a are partially exposed, a sixth step of etching each of the exposed first upper electrodes 15a by a specified thickness to form a second upper electrode 15b, and a seventh step of removing the resist 22.

摘要： A piezoelectric resonant filter comprises a chip having a plurality of thin-film piezoelectric resonators, and a mounting substrate on which the chip is mounted. The chip is mounted on the mounting substrate by flip chip bonding. A plurality of bumps provided on the chip are bonded to a plurality of conductors on the mounting substrate by interdiffusion between atoms, in a solid phase, of the respective metals of which the bumps and the conductors are made, without involving melting of the respective metals of which the bumps and the conductors are made. The chip has a series resonator and a parallel resonator each formed of a thin-film piezoelectric resonator. These resonators constitute a ladder filter circuit.
