摘要： An exemplary method for a producing a piezoelectric vibrating piece having at least one mesa step includes forming a metal film on a main surface of a piezoelectric wafer. A through-groove is formed through the thickness of the wafer to form a plan profile of a desired piezoelectric substrate. A film of photoresist is formed on the surface of the metal film. A resist is applied, exposed, and formed into a resist pattern that defines a first mesa step along at least a portion of the plan profile. In regions not protected by the metal film, the piezoelectric substrate is etched to a defined depth to form a mesa step. The denuded edge surface of the metal film is edge-etched. A second mesa step, inboard of the first mesa step, can be formed by repeating the edge-etching and substrate-etching steps using the metal film as an etch protective film.

摘要： Quartz-crystal devices are disclosed, of which the CI value is reduced by adjusting the shortest distance between an edge of electrically conductive adhesive and an edge of the excitation electrode. The device has a quartz-crystal plate having long-edges and short-edges. Excitation electrodes are on first and second surfaces of the plate. Conductive pads are electrically connected to respective excitation electrodes and extend to the short-edge of the quartz-crystal plate. A package having a pair of external mounting terminals and respective connecting electrodes are situated on opposing sides of the mounting terminals for making electrical connections to the mounting terminals. An electrically conductive adhesive bonds the connecting terminals and respective conductive pads together, and the quartz-crystal plate onto the package. The shortest distance between an edge of the adhesive and an edge of the excitation electrode is 10%-15% the length of the quartz-crystal plate in the long-edge direction.
