摘要： A method for manufacturing an electronic device includes the steps of forming a first resist pattern on a primary surface of a SAW element, the first resist pattern having openings at positions corresponding to those at which bumps and a sealing frame are to be formed, sequentially forming metals over the first resist pattern, the metals being formed into adhesion layers, barrier metal layers, and solder layers, removing the first resist pattern on the SAW element such that the bumps and the sealing frame are simultaneously formed. When the bumps and the sealing frame of the SAW element are bonded to bond electrodes of the bond substrate, the solder layers are melted and alloyed by heating.

摘要： 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.

The piezoelectric thin film resonator has a substrate, a thin film member, and reinforcing films. The thin film member has at least two support portions supported by the substrate and a floating portion disposed over the substrate with a space provided therebetween and supported by the support portions. The floating portion includes a pair of excitation electrodes facing each other and a piezoelectric thin film provided therebetween. The reinforcing films are formed in the vicinities of the boundaries between the floating portion and the support portions of the thin film member.
