摘要： In a surface-acoustic-wave (SAW) device and method of fabricating the same, a SAW chip is flip-chip mounted in a package. The package has a window facing an electrode formed surface of the SAW chip. After the SAW chip is mounted, the in-process item is inserted into reactive ion etching equipment, with the window open. The substrate or electrodes of the SAW chip is etched by an etching gas introduced into the ion etching equipment. Films may be formed on the electrode formation surface, in place of etching. Thus, variation in characteristics stemming from variations in manufacturing processes can be suppressed.

摘要： A surface elastic wave filter for processing a supplied signal into a signal with nonlinear-phase frequency characteristics has a piezoelectric substrate for propagating a surface elastic wave through a surface layer thereof and spaced input and output electrodes disposed on the surface layer for sending and receiving the surface elastic wave. Each of the input and output electrodes has a pair of common electrodes having comb-shaped interdigitating electrode fingers extending therebetween. The central electrode fingers of the input and output electrodes have central axes across the direction of propagation of the surface elastic wave. The distance along the direction of propagation between the central axes is varied in the direction substantially normal to the direction of propagation. The surface elastic wave filter may include an electric conductor disposed on the piezoelectric substrate between the input and output electrodes and having a dimension in the direction of propagation, the dimension being varied in the direction substantially normal to the direction of propagation. A medium for varying the speed of propagation of the surface elastic wave may be positioned in place of the electric conductor.

摘要： A surface acoustic wave device has a package and a surface acoustic wave element mounted therein face down. The package includes a side wall comprising linear inner side surfaces close to respective outer side surfaces of the surface acoustic wave element and recesses defined where the inner side surfaces of the side wall intersect at respective inner corners. When the surface acoustic wave element is inserted into the side wall along the inner side surfaces thereof, the corners of the surface acoustic wave element do not engage the side wall because of the recesses. Therefore, the outer side surfaces of the surface acoustic wave element may be positioned very closely to the inner side surfaces of the side wall. The surface acoustic wave device may be reduced in size, and the surface acoustic wave element may have input and output electrode pads and ground pads positioned highly accurately with respect to electrode pads on the bottom plate of the package.

摘要： A surface acoustic wave device and its manufacturing method. A surface acoustic wave device is used as filters for VHF and UHF range signals, or resonators for VHF and UHF range, by driving the surface of a surface acoustic wave element with applied signal to electrodes, transmitting a surface acoustic wave, and receiving the surface acoustic wave with other electrodes. In a configuration of a surface mount type surface acoustic wave device where a surface acoustic wave element is stored inside a package consisting of a base and a cover, pads are attached on a surface of the base and the surface acoustic wave element is fixed to the base by face down bonding.
