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.

摘要： In a piezoelectric device, a piezoelectric substrate includes a vibrating piece with respective excitation electrodes on each principal surface thereof. The piezoelectric substrate is surrounded by an outer frame separated therefrom by a through-void except for a supporting portion connecting the vibrating piece to the frame. Extraction electrodes extend from the excitation electrodes across the supporting portion to the frame, and on edge surfaces of the supporting portion. The piezoelectric substrate is sandwiched between a lid and a package base to form a piezoelectric device. The outer surface of the package base is a mounting surface to which the extraction electrodes extend via an edge surface of the through-void in a region that does not overlap the excitation electrode.

摘要： To provide a method for manufacturing a piezoelectric resonator which can conduct frequency matching with high reliability when performing rough adjustment of the frequency by adjusting the shape of a piezoelectric oscillating piece before forming an electrode film, and thereby it becomes possible to avoid reduction of the yield. Etching for forming the shape of a piezoelectric oscillating piece, and etching for forming grooves are conducted simultaneously, and after forming the grooves, the shape formation of the piezoelectric oscillating piece is started again from the same depth as the groove in a state of covering the groove with a metal film, and after the shape formation, matching of frequency is conducted by etching the side surface of the piezoelectric oscillating piece in succession. By composing such a structure, it is possible to conduct rough adjustment of frequency at a low etching rate so that the frequency matching can be performed with no due difficulty and with high accuracy.

摘要： To provide a method for manufacturing a quartz piece which can suppress the deterioration of the CI and the temperature characteristic failure by forming the end surface of the quartz piece perpendicularly. A method for manufacturing a quartz piece that has a shape having two sides facing each other from a quartz substrate, includes the steps of: forming an etching mask provided with an opening area for forming the outside shape along one side out of the two sides which face each other, and provided with no opening area on the other side out of the two sides facing each other, on one surface side of the quartz substrate; and forming an etching mask provided with an opening area for forming an outside shape along the other side out of the two sides which face each other, and provided with no opening area on the one side, on the other surface side of the quartz substrate. Formation of protrusions is reduced when, at the time of etching from one surface side of the quartz substrate, the rate of etching in the direction from the one side toward the other side is greater than the rate of etching in the direction from the other side toward the one side due to the anisotropy of quartz, and at the time of etching from the other surface side of the quartz substrate, the rate of etching in the direction from the other side toward the one side is greater than the rate of etching in the direction from the one side toward the other side due to the anisotropy of quartz.
